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)

Calculate the value of Ka(acid) if a 0.1 M solution of CH2ClCOOH has a pH of 2.
(a.) given pH, what is the [H+]?
(b.) given [H+], what is [CH2ClCOO-]?
(c.) What is the value of Ka?

#### Solution Preview

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.

Question 1:
Assuming the Pb2+ came ...

#### Solution Summary
