Chapter 21, Problem 21.47QP

(a)

Interpretation Introduction

Interpretation:

The balanced equations for the reaction of Al in basic solution with ${\text{NaNO}}_{\text{3}}$ has to be written.

Concept introduction:

• To write a chemical reaction from the given information we must understand which is going to react and which is going to form as product in a particular chemical reaction.
• First, write the half-reaction from the given information
• Write down the reactants in left side and analyze carefully the possibility of product obtain and that can be placed in right side of a reaction.
• We can represent a reaction by writing reactants in left side and products in the right side.

(b)
