Chapter 24, Problem 35QP

Interpretation Introduction

Interpretation:

The meaning of nitrogen fixation, and the process for the fixation of nitrogen on an industrial scale are to be described.

Concept introduction:

Nitrogen is a member of the group $5\text{A}$ or group 15(according to modern periodic table).

Nitrogen occurs as a diatomic gas in its elemental state, and is unreactive at room temperature.

It makes about 78% by volume of the atmosphere.

It is a colourless, tasteless and non-toxic gas.

Saltpeter ${\text{KNO}}_3$ and Chile saltpeter ${\text{NaNO}}_3$ are the most important mineral sources of nitrogen.

The conversion of atmospheric nitrogen into nitrogenous compounds is called nitrogen fixation.
