The answer is
The general reaction looks like this
The reaction that is of interest is actually this
In order to determine the maximum concentration of
The expression for
A precipitate will form when the solution is saturated with ions; if the concentrations of the ions are low enough, a precipitate will not form. The threshold for the formation of a precipitate implies that the above equation be satisfied.
For a saturated solution, on the verge of forming a precipitate, the maximum value for the product of the concentrations of the two ions is equal to
From this point on, any increase in the concentrations of the ions will result in the formation of the precipitate.
Since your reaction takes place in 1 L, 0.01 M
This means that the maximum concentration of
As a numerical value, I've found
