What is the balanced ionic equation for the reaction HCHO2 (aq) + KOH (aq)

Answer: The complete ionic equation is;

H⁺ (aq) CHO₂⁻ (aq) + K⁺ (aq) OH⁻ (aq) → K⁺ (aq) CHO₂⁻ (aq) + H₂O (l)

Net ionic equation is;

H⁺ (aq) + OH⁻ (aq) → H₂O (l)

Explanation: The balanced equation for the reaction between HCHO₂ and KOH is given by;

HCHO₂ (aq) + KOH (aq) → KCHO₂ (aq) + H₂O (l)

Ionic equation involves writing a balanced equation showing all the ions in a chemical reaction. The complete ionic equation will therefore be;

H⁺ (aq) CHO₂⁻ (aq) + K⁺ (aq) OH⁻ (aq) → K⁺ (aq) CHO₂⁻ (aq) + H₂O (l)

Net ionic equation on the other hand, shows only the ions that are directly involved in the reaction and omits the spectator ions. The net ionic equation will be;

H⁺ (aq) + OH⁻ (aq) → H₂O (l)
