Unformatted text preview: Simple Rules for the Solubility of Salts in Water 1) Most nitrate (NO 3-) salts are soluble. 2) Most salts containing the alkali metal ions (Li + , Na + , K + , Cs + , Rb + ) and the ammonium ion (NH 4 + ) are soluble. 3) Most chloride, bromide, and iodide salts are soluble. Notable exceptions are salts containing the ions Ag + , Pb 2+ , and Hg 2 2+ . 4) Most sulfates salts are soluble. Notable exceptions are BaSO 4 , PbSO 4 , Hg 2 SO 4 , and CaSO 4 . 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 (S 2-), carbonate (CO 3 2-), chromate (CrO 4 2-), and phosphate (PO 4 3-) salts are only slightly soluble.
