If 200 mL of some Pb(NO_{3})_{2} solution is mixed with 500 mL of 3.50 *x* 10^{−2} M NaCl solution, what is the maximum concentration of the Pb(NO_{3})_{2} solution added if no solid PbCl_{2} forms? (Assume K_{sp} = 2.00 *x* 10^{−5} M at this temperature.) Enter the concentration in M.

(Figure out the new concentration of Cl^{−} ions, after adding the two solutions, then calculate the unknown concentration from the K_{sp} equation)

Step 1

The initial concentration of Pb(NO_{3})_{2} is taken as x M. Then the concentration of Pb^{2+} in the solution is determined as given.

Step 2

The initial concentration of NaCl is 3.50× 10^{-2} M. Then the concentration of Cl^{-} in the solution is determined as given.

Step 3

Concentration of Pb(NO3)2 solution added can be calculated from the ex...
