Question

Equal lenghts of the magnesium ribbon are taken in test tube a and b. Hydrochloric acifd is added to test tube a while acetic acid is added to test tube b. In which test tube will the fizzing occur momre vigourosly and why

Answer 1

HCl is more strong acid as acetic acid is a weak acid....so Hydrogen bubbles will be formed more in HCl test tube causing more fizzing........

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.
