6.17: Ionic Compounds Containing Polyatomic Ions

In a crystal of calcium sulfate, for instance, there must be equal numbers of Ca 2+ and SO 4 2– ions in order for the charges to balance. The formula is thus CaSO 4. In the case of sodium sulfate, by contrast, the Na + ion has only a single charge. In this case we need two Na + ions for each SO 4 2– ion in order to achieve electroneutrality.
