What chlorides are insoluble?

Answer 1

Silver, lead, and mercurous chlorides.

#K_(sp)# for #AgCl# is #1.8xx10^-10#, for #PbCl_2#, #5.9xx10^-5#, for #Hg_2Cl_2#, #1.3xx10^(-18)#. Cuprous chloride is also reasonably insoluble, #K_(sp)# #=# #1.72xx10^-7#, but it does not generally appear on the standard tables of solubility.
