Compounds containing polyatomic ions are named similarly to those containing only monatomic ions, except there is no need to change to an –ide ending, since the suffix is already present in the name of the anion. Examples are shown in Table 1.1.
KC2H3O2, potassium acetate | (NH4)Cl, ammonium chloride |
NaHCO3, sodium bicarbonate | CaSO4, calcium sulfate |
Al2(CO3)3, aluminum carbonate | Mg3(PO4)2, magnesium phosphate |
