1. Write the complete ionic equation:
* KOH(aq) → K⁺(aq) + OH⁻(aq)
* H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq)
* K₂SO₄(aq) → 2K⁺(aq) + SO₄²⁻(aq)
* H₂O(l) → H₂O(l) (Water remains as a molecule)
Complete ionic equation:
2K⁺(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2H₂O(l) + 2K⁺(aq) + SO₄²⁻(aq)
2. Identify and cancel spectator ions:
* Spectator ions are ions that appear on both sides of the equation and do not participate in the reaction. In this case, K⁺(aq) and SO₄²⁻(aq) are spectator ions.
3. Write the net ionic equation:
2OH⁻(aq) + 2H⁺(aq) → 2H₂O(l)
Simplified net ionic equation:
OH⁻(aq) + H⁺(aq) → H₂O(l)
Therefore, the net ionic equation for the reaction is OH⁻(aq) + H⁺(aq) → H₂O(l). This equation represents the fundamental reaction between hydroxide ions and hydrogen ions to form water.
