When zinc metal is treated with a dilute solution of ex acid a gas is evolved which is utilised the hydrogenation of oil name the gas evolved with the chemical equation and also write a test to detect the gas formed.

when zn metal reacts with x = h2so4
znso4 is produced with a gas named hydrogen.
It can be tested by taking a lighted match stick near it.It will extinguish making a pop sound.
Hence,it is the required test to be done to recognise that the evolved gas is H. i.e hydrogen.

Zn + dilute acid -------------> Zn²⁺ + H₂
eg: Zn + H₂SO₄ -------------> ZnSO₄ + H₂
Here, Hydrogen gas is evolved.
It can be identified by its characteristic POP sound when a burning splinter or a lighter is brought near the gas.
This POP sound is because, Hydrogen gas is a supporter of combustion and burns when a burning splinter is brought near to it, thus producing the POP sound.
Hope it helps!!
