Question

Equal lengths of magnesium ribbons are kept in test tubes a &b ,hydrochloric acid is added a white acetic acid is added to test tube b amount and concentration of both the acid is same ,in which test tube will the fizzing occur more vigoriously and why

Answer 1

fizzing occurs more vigorously in a.
Because HCl is more reactive

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.
