In which of the following solutions will AgCl be least soluble?
A) 0.1M HCl
B) 0.15 M AgNO3
C) 0.08 M MgCl2
D) Pure Water




The correct answer is C. I believe this is because of the common ion effect, but HCl also contain Cl. Is the answer C because it contains more of the common ion? Or is it because it has a lower concentration? Thank you very much in advance.

there's more common ion in C.

Thanks alot, so the more common ion present, the lower the solubility?

For the purposes of the MCAT, yes.
