Answer
If we are given the name of ionic compounds with polyatomic ions, we determine the formulas by writing the symbol for the cations followed by the formula of the polyatomic ions. We then balance the charges to end with a net charge of zero. If the formula of such compound is given instead, then the name is given by writing the name of the cation followed by the name of the polyatomic ion, being always careful about the ending (-ate or -ite).
