Net ionic equation

Question

Write the net ionic equation for the chemical reaction shown. Include physical states.

HClO2(aq)+NaOH(aq)⟶H2O(l)+NaClO2(aq)

Answer 1

HClO2 (chlorous acid) is a weak acid and should not be ionized, so we will leave it when we write the ionic and net ionic equations.

HClO₂(aq) + NaOH(aq) ==> H₂O(l) + NaClO₂(aq) ... molecular equation

HClO₂(aq) + Na⁺(aq) + OH^-(aq) ==> H₂O(l) + Na⁺(aq) + ClO₂^-(aq) ... ionic equation

HClO₂(aq) + OH^-(aq) ==> H₂O(l) + ClO₂^-(aq) ... net ionic equation
