The measured molar solubility of AgCl in water is 1.3 x 10^-5 M. In the presence of Cl^-(aq) as a common ion at different concentrations, the measured solubilities of AgCl are as listed below.

[Cl^-], M:     0.0039     0.036     0.35     1.4     2.9     3.8 

Solubility of AgCl, M: 7.2 x 10^-7 1.9 x 10^-6 1.7 x 10^-5 1.8 x 10^-4 1.0 x 10^-2 2.5 x 10^-2

Give a plausible explanation for the trends in the molar solubilities of the AgCl.
