Question

How will you test whether the gas evolved in the reaction is hydrogen?

Answer 1

Hydrogen gas can immediately catch fire followed by the “pop sound”.So we can use this property of hydrogen gas to detect whether the hydrogen gas is getting evolved in a reaction or not.

Procedure:

1. Bring the burning match stick close to the mouth of the tube evolving the gas.
2. If it catches the fire accompanied by the “pop sound ” then it is hydrogen gas.

In this way, we can easily test the hydrogen gas evolving in the reaction.
