Question

How do you write "calcium hydroxlde + phosphoric acid yield calcium phosphate + water"?

Answer 1

`Ca(OH)_2 + H_3PO_4 -> Ca_3(PO_4)_2 + H_2O` (unbalanced)

Explanation:

Writing calcium hydroxide + phosphoric acid yield calcium phosphate + water in chemical equation would be,
`Ca(OH)_2 + H_3PO_4 -> Ca_3(PO_4)_2 + H_2O`

but it still needs to be balanced. To balance this, you just have to ensure that there is an equal amount of elements in both the reactant and product side.

Balancing this would result to,

`3Ca(OH)_2 + 2H_3PO_4 -> Ca_3(PO_4)_2 + 6H_2O`
