. 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.

Best Answer

Answer: When Zinc reacts with Dilute acid solution, the following reaction takes place, and hydrogen gas is evolved

Zn + 2HCl→ ZnCl2 + H2
When Hydrogen gas is brought near a burning flame, it burns with a popping sound, which is the confirmation for the evolution of Hydrogen gas.
