Thursday, Day 5
AP: we did a few acid-strength explanation problems; then, we moved on to the prediction and explanation of the acidity or basicity of a given salt. We learned that certain ions hydroyze water and that other ions do not; water hydrolysis results in either an increase or a decrease in the pH of the solution. We did a couple of pH calculation of acidic and basic salts by using conjugate pKa and pKb values.
Honors: we did the aforementioned Nuclear test. good times. There will be some stoichiometry/solutions hw over the weekend.
Regents: we did some more ppm and molarity calculations; then, we learned two more measures of concentration: percent by mass and percent by volume.
More text hw regarding solutions this weekend. There will be a solutions and stoichiometry test next week.
