Question:Sodium phosphate is added to hard water containing calcium ions.

please look at my answer and write the true version of it$.$

$=>C{a}^{2+}+N{O}_{3}P{O}_{4}C{O}_3(P{O}_4{)}_2+8N{a}^{+}$

Calcium phosphole with sodeum phosphate con be represented as follars

$8C{a}^{2+}+2P{O}_4^{-3}C{O}_3|P{O}_4{|}_2$

Brcabonale $=>2N{O}_{3}P{O}_4+8CO(HC{O}_3{)}_{2}C{O}_3(P{O}_4{)}_2+6N{a}_{2}HC{O}_3+$

Calcum Cabonale $N{O}_{3}P{O}_4+3COC{O}_{3}C{O}_3(P{O}_4{)}_2+3N{O}_{2}C{O}_3$
