Question

Write the reaction involve in the preparation of chlorine gas without the application of heat?

Answer 1

Explanation:

chlorine gas is Cl2. It is yellow-green in colour and has an odour which is similar to to the household bleach. It is soluble in water and reacts to form hypochlorous acid and hydrochloric acid.

Answer 2

Explanation:

1) We can prepare the gas by heating manganese dioxide along with concentrated hydrochloric acid. We can also prepare the gas by the activity of hydrochloric acid on bleaching powder (or) lead dioxide potassium (or) permanganate.

Chlorine

2) Electrolytic Process

We can acquire the gas by the electrolysis of salt water in a Nelson cell. This is the least expensive technique and gives the purest form of the gas.

3) Deacon’s Process

In this procedure, we can manufacture the gas by the oxidation of hydrochloric acid in the presence of cuprous chloride at 723K and a pressure of 1 atmosphere.
