Chapter 21, Problem 37PS

Interpretation Introduction

Interpretation:

To write the balanced chemical equation for the reaction of aluminium and sodium hydroxide and predict the volume of ${\text{H}}_{\text{2}}$ gas produced.

Concept introduction:

Aluminium belongs to group $\text{3A}$ of the periodic table. It react with a base like sodium hydroxide to produce sodium aluminate and hydrogen gas. There is evolution of heat and the reaction is highly exothermic. Hydrogen gas is released rapidly.

Ideal gas equation is,

$PV=nRT$

Where P, V, T, n, and R are the pressure, volume, temperature and amount of substance respectively.
