# Concentration of Pb2+ in 0.0010M KI Saturated with Pbl2

Formatted version is attached.

--------------------------

Find the concentration of Pb2+ in 0.0010M KI saturated with Pbl_2. Include activity coefficients in your solubility-product expression. The K_sp of Pbl_2 os 9.8 x 10^-9.

[Pb^2+] = _________M

Hint from the program:

K_sp=[Pb^(2+)] γ_(Pb^(2+))[I^-]^2 γ^2_(I^-)

Assume that [I-] = 0.0010 M. The ionic strength of 0.0010 M KI can be calculated, then used to find the activity coefficients from a table.
