Question

Write balanced complete ionic equation for the reaction 2k3po4(aq)+3nicl2(aq)→ni3(po4)2(s)+6kcl(aq). express your answer as a chemical equation.

Answer 1

2PO₄³⁻ + 3Ni²⁺ → Ni₃(PO₄)₂(s)

Step-by-step explanation:

In chemistry, an ionic equation is a equation in which the electrolytes in aqueous solution are expressed as dissociated ions. Solids are written as complete molecules, not ions.

For the reaction:

2K₃PO₄(aq) + 3NiCl₂(aq) → Ni₃(PO₄)₂(s) + 6KCl(aq).

Ionic equation is:

6K⁺ + 2PO₄³⁻ + 3Ni²⁺ + 6Cl⁻ → Ni₃(PO₄)₂(s) + 6K⁺ + 6Cl⁻

As K⁺ and Cl⁻ doesn't change, the ionic equation is:

2PO₄³⁻ + 3Ni²⁺ → Ni₃(PO₄)₂(s)
