Answer:

NO₂⁻ and Na⁺

Explanation:

  • The reaction between nitrous acid and sodium hydroxide is given by;

HNO₂(aq) + NaOH(aq) → NaNO₂(aq) + H₂O(l)

  • The complete ionic equation for the reaction will be;

H⁺(aq)NO₂⁻(aq) + Na⁺(aq)OH⁻(aq) → Na⁺(aq)NO₂⁻(aq) + H₂O(l)

  • The net ionic equation will be;

H⁺(aq)+ OH⁻(aq) → H₂O(l)

  • NO₂⁻ and Na⁺ are spectator ions and therefore they are not included while writing the net ionic equation.
  • Spectator ions are ions that do not change state after the reaction has taken place.
