Equation :

H2SO4+Zn —>ZnSO4+H2

Observations :

1)When dilute sulfuric acid is poured on zinc granules, then zinc sulfate is formed along with the evolution of a gas. Zinc is more reactive than hydrogen, so displaced it from sulfuric acid.

2)The gas evolved is hydrogen. We can test its presence by bringing a burning candle near the mouth of the test tube and hearing for a popping sound. Only hydrogen gas burns with a 'pop' sound.

The same observations will be found even in the case of Hcl
