Chapter 21, Problem 20PS

Interpretation Introduction

Interpretation: To predict the most suitable method for the production of large quantities of hydrogen form the given methodes.

Concept introduction: Hydrogen is a colorless gas and has a very low boiling point. It has very low atomic mass. Hydrogen is produced in vast quantities by various industrial methods, the majority of which is used for the preparation of ammonia by Haber’s process.

It is also used in the manufacturing of methanol and other chemicals.

The simplest way to generate hydrogen is through coal and steam. This is one of the oldest methods to synthesize hydrogen. The other methods to produce hydrogen are catalytic steam reformation of methane and electrolysis of water.

Some of the laboratory methods to produce hydrogen are the reaction of metal with an acid, metal hydride with water or metal with water. The most commonly used laboratory method is the reaction of metal with an acid.
