Solution

$H C l$ is a strong acid whereas $C H_{3} C O O H$ is a weak acid. Strong acid dissociates completely to form $H^{+}$ ions. Hence, HCl will react more vigorously.

Equal lengths of magnesium ribbons are taken in two test-tubes X and Y. Hydrochloric acid is added to test-tube X and acetic acid is added to test-tube Y.In which test-tube, the reaction will be more vigorous ? Why ?

HCl is a strong acid whereas CH3COOH is a weak acid. Strong acid dissociates completely to form H+ ions. Hence, HCl will react more vigorously.
