Complete the balanced molecular reaction for the following weak base with a strong acid:

Question

2 NaClO₂ (aq) + H₂SO₄ ->

Answer 1

The weak base is ClO₂^-

The strong acid is H₂SO₄

The strong acid will donate H⁺

The weak base will accept H⁺

ClO₂^- + H₂SO₄ ==> HClO₂ + HSO₄^-

If you want to include the second dissociation of H₂SO₄, then you'd have...

2ClO₂^- + H₂SO₄ ==> 2HClO₂ + SO₄^2- (without Na+ as the spectator ion)

Complete molecular equation:

2NaClO₂ + H₂SO₄ ==> 2HClO₂ + Na₂SO₄
