Q.4 ) Which gas is produced when dilute hydrochloric acid is added to a reactive metal? Write the chemical reaction when iron reacts with dilute H 2 SO 4 .


Metals react with Dilute Acid to form Salt and Hydrogen gas.
Hence, Hydrogen gas is produced when dilute HCl is added to reactive metal.

Reaction of iron with dilute H 2 SO 4
Iron reacts with dilute Sulphuric Acid to form Iron Sulphate and Hydrogen Gas.

2Fe (s) + 3H 2 SO 4 (aq) → Fe 2 (SO 4 ) 3 (aq) + 3H 2 (g)
