Which of the following salts is least soluble in water?

Which of the following salts is least soluble in water?

NiS, MgCl2, K2CrO4, Al2(SO4)3, Pb(NO3)2

The answer is NiS.

I know like dissolves like, but since they're all salts (ionically bonded), I don't quite know where to start. Please help me out!

Compounds of the 6th. group with transition metalls not solouble. Like Oxides, sulfides, selenides, etc.

Is that also part of the solubility rules?
