Question

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

Answer 1

Answer:

Net ionic equation:

H⁺(aq) +  OH⁻(aq)    →     H₂O(l)

Explanation:

Balanced Chemical equation:

HClO₂(aq)  + NaOH(aq)    →     H₂O(l) + NaClO₂ (aq)

Ionic equation:

H⁺(aq) +  ClO₂⁻(aq)  + Na⁺(aq) + OH⁻(aq)    →     H₂O(l) + Na⁺(aq) + ClO₂⁻ (aq)

Net ionic equation:

H⁺(aq) +  OH⁻(aq)    →     H₂O(l)

The  ClO₂⁻(aq) and  Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
