• A. True
• B. False

Answer 1

The correct option is A True

Calcium phosphate can be prepared by mixing solution containing calcium ions and hydrogen phosphate ions in the presence of an alkali.
$H{P{O}_4}^{2-}+{OH}^{-}\to {P{O}_4}^{3-}+H_{2}O$
$3{Ca}^{2+}+2{P{O}_4}^{3-}\to {Ca}_3{\left(P{O}_4\right)}_2$
