I'm looking at the solubility rules rule 1: C2H3O2 and NO3 are soluble rule 2: K, Na, and NH4 salts are soluble rule 3: Cl ions and halogens except for Hg2Cl2, AgCl, PbCl2 rule 4: SO4 except for BaSO4, CaSO4, PbSO4 rule 5: insoluble: OH except for NaOH, KOH, and CaOH, rule 6: insoluble: sulfide,...eport Abuse. ur Rule no. 3 is wrong..it is: all HALIDES are soluble ecxept those of Ag Pb and Hg (this is the rule taught at o and a levels)..halides include salts of all the halogens including iodine so AgI is insoluble.
