Equal lengths of magnesium ribbons are taken in test tubes A and B. Hydrocloric acid is added to test tube A, while acetic acid is added to test tube B. The amount and concentration taken for both the acids are same. In which test tube does the reaction occur more vigourously and why?

Solution
Since, HCl acid is much stronger than acetic acid (CH3COOH), therefore in test tube A reaction occurs more vigorously because due to strong acidic nature of HCl,Mg can be easily displaced as compared with the reaction of Mg and acetic acid.
