Question

A reaction that is used to make ClO2 is:HCl + NaOCl +2NaClO2 2ClO2 + 2NaCl + NaOHa) Which element is oxidized? b) Which element is reduced? c) Which substance is the oxidizing agent and which is the reducing agent?

Answer 1

Given the following reaction:

$\text{HCl + NaOCl + 2NaClO}_2\text{ }\rightarrow2ClO_2\text{ + 2NaCl + NaOH}$

We want to know the element oxidized, the element reduced and the substance that is the oxidizing agent and a reducing agent.

Answer:

a) Element Oxidized = Na

b) Element reduced = Cl

c) NaClO is an oxidizing agent and HCl is a reducing agent.
