1. Calculate the Ksp of a saturated solution if it contains 0.0001 M Pb2+.
2. CH2ClCooH(aq) --(Forward/Reverse reaction)--H+ (aq) + CH2ClCOO- (aq)
To answer these two questions, you need to identify the types first. Your first question is a relatively simple Ksp problem (although you have left out the anion in the complex), and your second question is a weak acid problem.
Assuming the Pb2+ came from a ...
The solution is given step-by-step equationally with some short explanations.
