Q.10: 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. In which test tube will the fizzing occur more vigorously and why?

 

Answer:-

In test tube A, fizzing occur more vigorously. It is because HCl is a stronger acid than acetic acid and therefore, produces H2 gas at a faster rate due to which fizzing occurs.
