Question

What is the net ionic equation for the acid-base reaction between chlorous acid and sodium hydroxide?

Answer 1

Answer:
`HCO_2(aq)+OH^-(aq)\rightarrow ClO_2^-(aq)+H_2O(l)`

Step-by-step explanation:

Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The reaction of chlorous acid (weak acid) and sodium hydroxide (strong base) is written as:

`HClO_2(aq)+NaOH(aq)\rightarrow NaClO_2(aq)+H_2O(l)`

The equation can be written in terms of ions as:

`HClO_2(aq)+Na^+(aq)+OH^-(aq)\rightarrow Na^+(aq)+ClO_2^-(aq)+H_2O(l)`

The ions which are present on both the sides of the equation are sodium ions and hence are not involved in net ionic equation.

Hence, the net ionic equation is :

`HCO_2(aq)+OH^-(aq)\rightarrow ClO_2^-(aq)+H_2O(l)`
