When zinc metal is treated with a dilute solution of a strong acid, a gas is evolved, which is utilised in the hydrogenation of oil. Name the gas evolved. Write the chemical equation of the reaction involved and also write a test to detect the gas formed.
Following reaction takes place when zinc is treated with a dilute solution of a strong acid.
Zn +H2SO4→ ZnSO4 + H2
In this reaction, hydrogen gas is produced; which is utilized in the hydrogenation of oil. When a burning matchstick is brought near hydrogen gas, the matchstick burns with a pop sound. This confirms the evolution of hydrogen gas.
