Detailed Solution

Hydrogen gas is released when zinc granules are treated with dilute H2SO4
When an acid and metal react, salt is created, and hydrogen gas is released. When zinc comes into contact with diluted sulfuric acid, hydrogen gas and zinc sulphate (ZnSo4) are released at room temperature. When zinc metal and sulfuric acid interact, a type of reaction called a displacement reaction occurs. Hence, H2 gas is released when zinc granules are treated with dilute H2SO4.
