The chemical formula Na₃PO₄ represents sodium phosphate. When dissolved in water, it dissociates into its ions. The dissociation equation is:
Na₃PO₄ (aq)→3Na⁺ (aq)+PO₄³⁻ (aq)
Ions Present in Solution:
- Sodium ions (Na⁺\): Three sodium ions are produced for each formula unit of sodium phosphate.
- Phosphate ions (): One phosphate ion is produced for each formula unit of sodium phosphate.
So, the solution contains and PO₄³⁻ ions.
