In which of the following solutions would solid PbCl2 be expected to be the least soluble at 25°C?

A) 0.1 M KNO3 B) 0.1 M HCl C) 0.1 M NaCl D) 0.1 M CaCl2

The answer is D.

I just don't understand why it is D.  Is it because like cannot dissolve like?  CL2 makes the two similiar so therefore less soluble?

Thanks!
