Answer:

Preparation of Dihydrogen

Laboratory Preparation of Dihydrogen

Reacting Zinc with Acid

One common way to prepare dihydrogen gas in the lab is by reacting Zinc with a diluted acid. It results in Zinc forming Zinc Sulphate (or zinc chloride) and releasing hydrogen in a gas form

Zn + H2SO4 → ZnSO4 + H2

Zn +HCl → ZnCl2 + H2

Reacting Zinc with Alkaline

Zinc can also react with an aqueous alkali such as Sodium Hydroxide, The sodium and zinc will combine and give us dihydrogen as another product. The reaction is as follows

Zn + 2NaOH → Na2ZnO2 + H2

Dihydrogen is used in the manufacture of vanaspati fat and in the manufacture of bulk organic chemicals like methanol. It is also used in the manufacture of hydrogen chloride and metal hydrides.
