Question

IN which reaction is hydrogen gas liberated ? describe with help of an activity

Answer 1

In a displacement reaction hydrogen gas can be liberated.

This can be explained as,

Those elements which are above H in reactivity series can displace H from its solution.

For example:

HCl + Na ----> NaCl + H

Answer 2

In response to electrolysis hydrogen gas is released with the help of a function is:

• When hydrochloric acid is purified or refined sulfuric acid reacts with metals placed above the hydrogen in a series of operations, the hydrogen gas is released.

• Active metals such as magnesium, zinc, iron etc., react with dilute hydrochloric acid or mix sulfuric acid to release hydrogen gas.

• Electrolysis of Water is the process of using electricity to convert water into oxygen and hydrogen gas through a process called electrolysis.

• Hydrogen gas released in this way.

• It can be used as hydrogen fuel, or regenerated with oxygen to form ox hydrogen gas, which is used in heating and other applications.
