Most nitrate salts are soluble. Most salts containing alkali metal ions and the ammonium ion are soluble. Most chloride, bromide, and iodide salts are soluble. Notable exceptions are salts containing the ions silvver, lead, and mercury (I). Most sulfate salts are soluble. Notable exceptions are salts containing the ions barium, lead, mercury (II), and calcium. Most hydroxide salts are nearly insoluble. The important soluble hydroxides are sodium hydroxide and potassium hydroxide. The compounds barium hydroxide, strontium hydroxide, and calcium hydroxide are marginally soluble. Most sulfide, carbonate, chromate, and phosphate salts are nearly insoluble.
