Question

# What is the formula for calcium hydroxide?

Solution

## To make a neutral species, we simply balance the charges. To balance the charge of the metal ion, $$Ca^{2+}$$ we need 2 hydroxide ions $$2 \times OH^-$$We get the formula $$Ca(OH)_2$$ Note that once you know the formula for calcium hydroxide, you know the formula for the hydroxides of ALL the Group 2 metals, i.e.$$Ba(OH)_2 ,Sr(OH)_2$$ General Knowledge
