Simple Rules for the Solubility of Salts in Water
1. Most salts containing nitrates (NO3-), hydrogencarbonates (H2CO32-), or ethanoates (-CH2CO2C2 H5) salts are
soluble.
2. Most salts containing alkali metal ions (Li +, Na+, K+, Cs +, Rb +) or the ammonium ion (NH4+) are soluble.
3. Most chloride, bromide, and iodide salts are soluble. Notable exceptions are salts containing Ag +, Pb2+, and
Hg22+ ions.
4. Most sulfate salts are soluble. Notable exceptions are BaSO4, PbSO4, HgSO4, and CaSO4.
5. Most hydroxide salts are only slightly soluble. The important soluble hydroxides are NaOH and KOH. The
compounds Ba(OH)2, Sr(OH)2, and Ca(OH)2 are marginally soluble.
6. Most sulfide (S2-), carbonate (CO32-), chromate (CrO42-), and phosphate (PO43-) salts are only slightly soluble.
