Question

Equal length of Magnesium ribbons are taken in test tubes A and B Hydrochloric acid is added to test tube a, while acetic acid is added to test B. In which test tube will the fizzing occur more vigorously and why?

Answer 1

The fizzing action occurs in test tube A

Because Mg reacts with HCl to give salt of Mgcl2 and H2 gas is liberated... creating the fizzing action...

HOPE IT HELPS...

Answer 2

The fizzing action will happen more vigorously in test tube A, as MG is a base and HCL is a acid .As acids and bases react to give hydrogen generally , so the test tube will fizz more vigorously.
