Nitrates (NO3-), acetates (C2H3O2-), and chlorates are soluble. Most chlorides (Cl-) are soluble, except those of silver (Ag+), mercury(I) (Hg2+), and lead (Pb). Lead (II) chloride (PbCl2) is soluble in hot water. Most sulfates (SO42-) are soluble, except those of barium (Ba), strontium (Sr), lead (Pb), calcium (Ca), and mercury (Hg). Most carbonates (CO32-), phosphates (PO43-), and silicates are insoluble, except those of sodium (Na), potassium (K), and ammonium (NH4+).
