Answer:

a) 0.0265M

b) 8.35×10^-4M

c) 9.833×10^-8M

Explanation:

First we must write down the equation of each reaction. After identifying the insoluble precipitate, we go ahead to write down the expression for its solubility product. If the solubility product of the compound is known, the concentration of the precipitating agent can now be calculated from the available information in the question.
