Laboratory Preparation of Dihydrogen is given below:
- Reacting Zinc with Acid - One common way to produce or prepare dihydrogen gas in the lab is by reacting Zinc with a diluted acid.
\(Zn + H_2SO_4 → ZnSO_4 + H_2\)
\(Zn +HCl → ZnCl_2 + H_2\)
- Reacting Zinc with Alkaline - Zinc can also react with an aqueous alkali such as Sodium Hydroxide, The sodium and zinc will combine and produces dihydrogen as another product. The reaction is given as:
\(Zn + 2NaOH → Na_2ZnO_2 + H_2\)
- Commercial Preparation of Dihydrogen - The commercial preparation of hydrogen is a huge industry due to the high demand for hydrogen in the production of fertilizers and the oil-refining process.
- Electrolysis of Water
- Lane’s Process
- From Natural Gas
