Question

Equal length of magnesium ribbon are taken in a test tube A and D hydrochloric acid is length p magnesium ribbon are taken in a test tube A. While acetic acid is added to test tube B. Amount and concentration taken for both the acids are same. In which test tube will be fizzing occur more vigorously and why?

Answer 1

In test tube a bcoz it is more reqctive5

Answer 2

Answer:

please mark me as brainliest please

Fizzing will occur more vigorously in test tube A. Hydrochloric acid (HCl) is a strong acid whereas acetic acid (CH3COOH) is a weak acid. Being strong acid, the hydrochloric acid solution contains a much greater amount of hydrogen ions in it due to which the fizzing will occur more vigorously in test tube A (containing hydrochloric acid). The fizzing is due to the evolution of hydrogen gas which is formed by the action of acid on the magnesium metal of magnesium ribbon.
