Question

what are the observations when zinc granules react with dilute sulphuric acid

Answer 1

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.

Answer 2

☺ Hello mate__ here is your answer...

Reaction:--

Sulphuric acid + Zinc → Zinc sulphate + Hydrogen

Balance reaction:-

H2SO4(aq) + Zn (s) ------> ZnSO4(aq) + H2(g)

I hope, this will help you

Thank you______❤
