To receive full credit for a problem, you must have a correct method, and you must check all approximations. For each problem, put a box around your final answer.
All reactions are balanced.
Only use activity coefficients in Problem 1. 1. To this solution was added 15.00 mL of 0.0100 M NaOH solution. The pH of the new solution was measured to be 4.000. Find the pK a of the acid. We would like to separate the two metal ions by selectively precipitating only one of them.
