Answer: first we place the mixture in water; since ammonia is highly soluble in water it dissolves leaving ethene and hydrogen gas which are slightly soluble in water to pass through as a gas.

Explanation: the water helps to collect the ammonia gas

To separate ethane, hydrogen, and ammonia to obtain hydrogen, the following procedure is followed.

  • The mixture is first passed through the water as ammonia is highly soluble in water, it will dissolve into it.
  • Now ethane and hydrogen will remain, to separate these gases, the fractional distillation method can be adopted.
  • In fractional distillation, the first mixture is cooled until liquid is formed. Then it is followed by heating. The gas with a lower boiling point rises in the distillation column and thus gases get separated.
  • The boiling point of hydrogen is

- 252.9 °c and the boiling point of

ethane is - 89°c. Hence hydrogen

having a lower boiling point will rise

in a distillation column.

  • Another method to separate hydrogen and hydrocarbon is to separate them electrochemically.
  • Partial condensation is also the simplest way to separate hydrogen from other hydrocarbons.
