Question

The oxidizing agent for the forward reaction in the equation is:Al+NO₂ Al(OH)4 + NH3A) AIBCDNO₂Al(OH)4NH3

Answer 1

`B`

Step-by-step explanation:

Here, we want to get the oxidizing agent in the forward reaction

By definition, the oxidizing agent is the reactant that undergoes reduction

Reduction is simply a gain in electrons. This simply means that the oxidation number decreases or becomes more negative for the substance undergoing reduction

Now, let us look at the reactants:

The nitrogen went from an oxidation number of +3 in NO2- to -3 in NH3

This means it has undergone reduction and it is the oxidizing agent
