Thurs-Day 6
AP: we had our last regular-season test and then we gained some practical lab experience.
We did a redox titration of hydrogen peroxide with potassium permanganate. We also transformed dichromate into chromate by adjusting the pH of the solution. Then, we burned stuff.
Honors: we worked with each permutation of the titration equation and solved for either molarity, volume, moles, or grams. We did problems involving both monoprotic and polyprotic acids. We then defined pH as related to the concentration of [H+] in solution. We drew a chart in which we related hydronium and hydroxide concentrations to Kw and to pH and pOH.
Regents: we did several different types of quantitative titration problems. We then defined pH and developed a chart in order to see the pattern of acidity and basicity as related to pH, [H+], and[OH-].
