Question

Magnesium ribbons of same size are taken in test tube A and b.HCL acid is added to test tube Awhile acetic acid is added to test tube B.The concentration of both the acids is same.in which test tube will fixxing occur more vigorously?why?

Answer 1

both fix with equal speed because both acids are having same concentration

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.
