3.1: Types of Chemical Compounds and their Formulas

Aug 25, 2020· A The calcium ion is Ca 2 +, and the hypochlorite anion is ClO −. B Two ClO − ions are needed to balance the charge on one Ca 2 + ion, giving Ca(ClO) 2. The subscripts cannot be reduced further, so the empirical formula is Ca(ClO) 2. This is calcium hypochlorite, the “chlorine” used to purify water in swimming pools.
