PRT 1220Acid-Base Titrations; Solubility

Foreword

We (finally) finish our detailed study of acids and bases with acid-base titrations. Like calculations involving buffer solutions, calculations for acid-base titrations aren't particularly difficult, but there are a lot of details to keep straight. We end the week with our first good look at solubility equilibria. Especially because of the July 4 holiday and variability in peoples' schedules, assignments this week are due only on Sunday, July 9. However, trust me: You will hate yourself and this material if you put all of it off until Sunday the 9th!

Questions and Answers

Whatever you're struggling with this week, somebody else in our section probably is struggling with it, too. Post your question on the Module 8 Q&A Board.

If you know the answer to someone's question, post it. It's almost a certainty that more people in our section than just the person who posted the question want to know the answer.
