Usually soluble
Group 1 and ammonium salts are soluble. Nitrates and acetates are generally soluble. Chlorides, bromides and iodides are usually soluble except certain Ag⁺, Pb²⁺ and Hg₂²⁺ salts.
Often insoluble
Carbonates, phosphates and most hydroxides are generally insoluble except with group 1 or ammonium ions. Sulfates are often soluble, but BaSO₄ and PbSO₄ are poorly soluble. Always consult measured data for borderline cases.
