Question

What metal chlorides are insoluble?

Answer 1

All HALIDES are SOLUBLE, except for those of `AgX`, `Hg_2X_2`, and `PbX_2`

Explanation:

Classic solubility rules holds that the halides of `Ag^+`, `Hg_2^(2+)`, and `Pb^(2+)` are water insoluble. Silver halides form a curdy white precipitate.
