# What is the covalent compound formula for calcium hydroxide?

Jan 14, 2017

$O {H}^{-}$

#### Explanation:

I think there is some confusion in your question. Calcium hydroxide consists of an ionic bond between a calcium ion, $C {a}^{2 +}$ and a hydroxide ion, $O {H}^{-}$.

The hydroxide ion itself has a single covalent bond between the oxygen and the hydrogen atoms, and so it is a covalent compound ion.
