Question

What is the covalent compound formula for calcium hydroxide?

Answer 1

`OH^-`

Explanation:

I think there is some confusion in your question. Calcium hydroxide consists of an ionic bond between a calcium ion, `Ca^(2+)` and a hydroxide ion, `OH^-`.

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