What we did in chemistry today…
Today we started with a little review of equilibrium and Le Chatelier’s principle using some worksheets from the Chem 1 textbook. Then we extended those concepts to talk about Ksp and the solubility of ionic compounds. (Next year, hope to include the barium chromate + acid demo to show how pH affects solubility – maybe [...]
Today I was absent. You worked on this review/ study guide all period.
Today I lectured almost the whole class…ugh…but there were so many questions!! Anyway, we started with the neutralization page of the study guide I’d handed out awhile back (so many of you had lost it!). I changed a couple in the box part so that some of the salts produced would change the pH (titration [...]
Today I handed out some review stuff for Environmental(study guide of air pollution + study guide for waste + practice q’s) so if you’d like to get working on that, please do! We’ll spend one class (next Mon. or Wed.) working on it. The rest of class we spent working on buffers (notes and problems). [...]
