Mg metal is reacted with HCl to produce hydrogen gas. This recording collects the data using a pressure probe, but low tech procedures are also presented. The goal is to calculate the molar volume of a sample of hydrogen gas which should be in agreement with the accepted value of This laboratory exercise satisfies procedure 12 of the 22 recommended procedures for AP Chemistry.

This protocol utilizes methods of integrated rate law to determine the order of the crystal violet reactant and the rate constant for the reaction between crystal violet a biological stain and sodium hydroxide. The procedure is then repeated at various temperatures so the data may be graphically analyzed in order to calculate the activation energy for the reaction using the Arrhenius equation.

The protocol utilizes a laboratory technique referred to as "swamping". It's my favorite of the 22 procedures! This lab satisfies lab procedure number 4 for the AP Chemistry course. The molar mass of lauric acid is experimentally determined using the method of freezing point depression. This lab should accompany a unit on solution chemistry, colligative properties or intermolecular forces.

This particular lab satisfies 9 in the recommended list of laboratory procedures in the AP Chemistry Course Outline. The technique used in this lab involves the method of continuous variations to determine the mole to mole ratio for a set of reactants. Welcome to one of the easiest units in all of AP Chemistry.

So easy in fact that you may find yourself studying this independently in an effort to buy more time for the more difficult units or simply catch up prior to the AP Chemistry Exam in May.

If that is indeed the case, be sure to write down any questions you have for your teacher! This channel is intended for students and teachers of AP Chemistry. It is designed to serve as a supplement to your AP Chemistry course and in no way designed to be a replacement for an actual AP Chemistry class. These instructional videos screen….

Heads up: the shoutbox will be retiring soon. You can still send a message to the channel owner, though!Iron II has a positive two charge:. Phosphate has a negative three charge:. The initial compound must be constructed to cancel these charges. The dissociation is:. Lead II hydroxide dissociates according to this reaction:.

Solubility is equal to the number of moles that will dissociate at equilibrium, and can be found using this reaction and the value of K sp. Which of the following factors will generally lead a solute to dissolve more easily into a solution i. Increasing the temperature of a solution will generally increase its solubility, while decreasing temperature will have the opposite effect. The common ion effect refers to the phenomenon when two compunds in a solution dissociate to produce at least one similar ion, and will make it harder for additional amounts of that ion in the solution to dissociate, decreasing solubility.

If the K sp of the above dissociation is found to be 2. First, set up a balanced reaction and enter X for the amount of each solute that is going to be dissolved.

As NaCl dissociates, each ion amount will increase by some amount, X. Remember that NaCl si not included in the equation, as it is a pure solid. If the solubility of CaF 2 in the dissociation reaction above was determined to be 1. Use the balanced reaction of the dissociation to assign values of X for the solubility of each ion. Use the given value for solubility to find K sp.

Consider the following balanced equation for the solubility of barium hydroxide in an aqueous solution. In order to solve for the solubility of barium hydroxide, we need to establish an ICE table for the reaction. Initially, there are no barium ions or hydroxide ions in the solution, so we can call their concentrations zero at the beginning of the reaction. For every molecule of dissolved barium hydroxide, there will be one ion of barium and two ions of hydroxide. Finally, we plug these values into the equilibrium expression and set it equal to the solubility product constant.

Four different insoluble salts are added to an aqueous solution in equal amounts. Assume that the salts do not interact with one another in any way. The following list shows the salts and their solubility product constants. The solubility product constants help us envision which ions will have the largest concentrations after dissolving to equilibrium.

Consider the following balanced equation for the dissociation of barium hydroxide in an aqueous solution. A 1M solution of barium nitrate is added to the solution.

What is the solubility of barium hydroxide after this addition? Before we solve for the solubility, remember Le Chatelier's principle.Easy to install and set up.

Edward and Irene, Canada Norway Complete, October 2016 It took all the effort out of organizing a trip. Normally I spend weeks, researching and making selections, but this was so easy, and so successful. I should add that I booked late, on impulse, contacting Bjarni on Sept. So glad we went in the early part of Oct. We would have preferred the beer package - beer and Norwegian food are great together, and the drinks on board were extremely expensive - we shared a beer at dinner.

I was a little intimidated by the title "Expedition" team, but that actually turned out to refer to a wonderful team of 4 who organize tours, hikes, lectures, music (and dancing. Bring lots of money.Many theoretical aspects that were known in the past have been empirically implemented with wonderful exercises of Mr. I have never had an online class before, and I have typically heard bad things about them, so I was shocked when I found out just how easy this course was to manuever.

I really liked the format - it allowed me to work at my own pace yet still check in with the teacher and the other students.

A really great experience for my first online course. Both the instructor and the teaching assistant were approachable, helpful, and knowledgeable about the subject matter, and provided constructive feedback about discussion board posts and assignment submissions. The textbook will be a valuable resource for future projects. He interacted meaningfully with students throughout the week. Was open to all questions and Displayed expertise of material. Would take another course with him. Iterative grading was helpful.

Thank you so much Professors for this useful course. I very much liked XLMiner, it is indeed a very simple yet powerful toolI was really impressed with the clarity, knowledge, engagement level, and patience of the instructor. His contribution in the forums made this the most useful online learning experience I've had (and I've tried a few different venues)I like the course very much and the material given to us was excellent.

I enjoy very much learning about simulations and using Cristal ball software. Also this course has given me valuable information about how to approach a risk analysis, and the software model assistant is very interestingI found it challenging but also a rewarding experience.

After completing this course I am now more confident about undertaking statistical analysis. Since I started the Epidemiology Statistics class, I've had a much better understanding of the other staffs' concerns. A very nice introduction to the subject.

As someone without any real background in epidemiology, now moving into an area where I need it, this course was very helpful indeed. This course is a great review of some popular probability distributions and how to test their assumptions. Reviewing the sampling techniques and testing the assumed distributions will help me when I check data and perform regression models. I appreciated the discussion board feedback as well as comments back on the homework assignments. Both of those things have helped me become a more efficient programmerDr.

Pruim was an outstanding instructor, extremely knowledgeable, respectful and prompt. This course has given me a strong foundation for continued learningThis is really a fantastic course. The materials were well done and the exercises really helped me develop and apply the concepts.

Very, very well done. I will recommend it to my colleaguesI was very impressed with how well Randall Pruim interacted with the class through the discussion forum. I also was pleasantly surprised at how smoothly all the logistical "on-line" issues went. I have already signed up for another courseI like the format of those courses.

AP Chemistry : Solubility and Equilibrium

There is a lot to learn, but it's concentrated on the key points. For somebody working full time it beats a semester-long course. Great pace to the course, nice and concise within 3 weeks, enjoyed the discussions, HW was not too intense and time consumingIt will help me to better understand the methods behind statistical analysis used for conducting research and publishing data.

I enjoyed the course. It's really convenient to do assignments on my own time. As always, professor Everson always provides nice feedback and suggestions to help understand the concepts very well.Scenario Your high schooler comes home smelling of alcohol or cigarette smoke for the first time.

What to Say The response should be measured, quiet and serious not yelling, shouting or overly emotional. Research shows that kids are less likely to use tobacco, alcohol and other drugs if their parents have established a pattern of setting clear rules and consequences for breaking those rules.

Kids who are not regularly monitored by their parents are four times more likely to use drugs. Make it clear that you disapprove of all alcohol, tobacco and drug use.

As teens are extremely concerned with their physical appearance, remind your teen about the negative effects alcohol, tobacco and other drugs have on physical appearance. Let your teen in on all the things you find wonderful about him. He needs to hear a lot of positive comments about his life and who he is as an individual and not just when he makes the basketball team or does well on a test.

Positive reinforcement can go a long way in preventing drug use among teens. Encourage your teen to volunteer somewhere that he can see the impact of drugs on your community.

Teenagers tend to be idealistic and enjoy hearing about ways they can help make an impact. Help your teen research volunteer opportunities at local homeless shelters, hospitals or victim services centers. What to Say to Your Young Adult About Drugs (19-25 yearolds) As you prepare your child for life after high school, you can help guide her to a healthy experience while still supporting her independence.

Tips for Conversations with Your Young Adult Make sure you keep an open line of communication with your child as she leaves home. Your child needs to know that if any problems or difficult situations arise, she can turn to you for help.

Be an at-home resource for your college student. Stay alert to possible mental health issues. There is a strong link between mental and physical health issues (including stress) and the use of drugs and alcohol. Just in case something does happen, make sure you know what campus mental health resources are available to your child and make sure they know, too.

While the most popular drugs on college campuses are alcohol and marijuana, non-medical use of prescription stimulants, analgesics (painkillers), and tranquilizers is on the rise.

Though prescription drugs do have an important role when prescribed by a doctor, unsupervised use of them can be extremely harmful.
