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 same. In which test tube will the fizzing occur more vigorously and why?

Answer:

Fizzing will occur more strongly in test tube A than in test tube B. As test tube A contains hydrochloric acid (HCl) which is a strong acid that reacts vigorously with magnesium whereas acetic acid  CH3COOH is weak acid. Being a strong acid, therefore hydrogen gas evolved a faster speed that's why it's more fizzing occurs.
