Question

which of the following method is used to produce dihydrogen of high degree purity ( >99.95% ) in the maximum amount?

Answer 1

Answer: OPTION 2

Explanation:

Answer 2

Answer:

• Option- b is correct Answer.

Explanation:

$\rule{300}{1.5}$

On large scale the Hydrogen (H₂) is produced by electrolysis of water using carbon electrodes.

But for High degree of purity warm solution of Barium Hydroxide (Ba(OH)₂) is electrolysed between Nickel (Ni) Electrodes.

Therefore, Option - 2 is Correct.

Properties of DiHydrogen:

• Hydrogen is neutral i.e. it has no effect on litmus paper.

• Hydrogen is not reactive at Room temperature.

• It forms Metal Hydrides, when it reacts with Metals.

• It can also reduce Metal from their oxides.

• It is an excellent fuel, it has a high calorific value.
