Question :

Equal lengths of magnesium ribbons are taken in test tubes A and B. Hydrochloric acid (HCl) is added to test tube A, while acetic acid (CH3COOH) is added to test tube B. Amount and concentration taken for both the acids are equal. In which test tubes A and B will the fizzing occur intensely and vigorously. Give reasons.

Answer :

HCl is a stronger acid than CH₃COOH.
Therefore, the H+ ions concentration in test tube A will be higher than in test tube B.
Hence, the reaction will occur faster in test tube A than in test tube B.
So, fizzing will occur more vigorously in test tube B.
