Complete this equation for the dissociation of K3PO4 (aq). Omit water from the equation because it is understood to be present.

Balanced chemical reaction (dissociation) : K₃PO₄ (aq) → 3K⁺ (aq) + PO₄³⁻ (aq).

K₃PO₄ is potassium phosphate, a water-soluble ionic salt.

In water potassium phosphate, ionic compound, dissociates on positive potassium ion (cations) and negative phosphate ions (anions).

Potassium has positive charge (+1), compound has neutral charge.
