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.

2PO₄³⁻ + 3Ni²⁺ → Ni₃ (PO₄) ₂ (s)

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)
