Concept behind it..
Zinc is more reactive than hydrogen and it displaces hydrogen from diluteacids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.
Results..
The zinc will react with sulphuric acid forming zinc sulphate dissolved in solution and releasing hydrogen gas.
Zn (s) + H2SO4 (aq) ---> ZnSO4 (aq)+ H2 (g)
When we take the test tube containing zinc and sulphuric acid near a candle or a burner, we hear a pop sound. This shows the presence of Hydrogen .
Also, if we take the the test tube near a litmus paper, the color remains same. This shows that hydrogen is neither acidic nor basic in nature. It is neutral in nature.

zn is an active metal ..
so as per typical reaction of acid.....
when metal react with acid it form salt and hydrogen....
so gas evolved is hydrogen
