Detailed Solution

When zinc granules are treated with dilute H2SO4, they will form zinc sulphate and hydrogen gas.
The metal zinc is present in the reactivity series of the metals. When zinc granules react with the dilute solution of sulphuric acid then the displacement reaction will take place and it will lead to the formation of ZnSO4 and the liberation of H2 gas takes place.
The reaction is :
Zn(s) + H2SO4(aq) → ZnSO4(aq) +H2 (g)
