Question

Acetylene gas is stored in a cylinder in which form?

Answer 1

• The formula of acetylene is $\mathrm{CH}\equiv \mathrm{CH}$.
• It is a colourless gas which has a mild ether-like odour. It is easily soluble in water, chloroform, acetone, and benzene.
• Acetylene is highly unstable and inflammable and would explode at elevated pressures.
• Due to the danger of explosion acetylene cannot be compressed to high pressure and thus it is stored in cylinders in the form of ‘dissolved acetylene’.

Therefore, acetylene gas is stored in cylinders in liquid form.
