5. apply determine the names of kclo, kio₄, nabro₃, and naclo₂.

Brief Explanations:

For ionic compounds, name the cation first followed by the anion. For oxy - anions, use specific naming rules.

1. In KClO, the cation is potassium (K⁺) and the anion is hypochlorite (ClO⁻), so it is potassium hypochlorite.
2. In KIO₄, the cation is potassium (K⁺) and the anion is periodate (IO₄⁻), so it is potassium periodate.
3. In NaBrO₃, the cation is sodium (Na⁺) and the anion is bromate (BrO₃⁻), so it is sodium bromate.
4. In NaClO₂, the cation is sodium (Na⁺) and the anion is chlorite (ClO₂⁻), so it is sodium chlorite.

Answer:

1. Potassium hypochlorite
2. Potassium periodate
3. Sodium bromate
4. Sodium chlorite
