Question

equal length of magnesium ribbon are taken in a test tube A and B hydrochloric acid is added to the test tube a while acetic acid is added to the test tube be amount and concentration of both the acid are the same in which test tube will the fizzing occur more rigorously and why

Answer 1

in which u add more strong acid .... which is HCl ...so in test tube a

Answer 2

we know that hydrochloric acid is a strong acid where is acetic acid is a weak acid. therefore hydrochloric acid has a large concentration of hydrogen ions. therefore fizzing will occur more vigorously in test tube am as fizzing is due to evolution of hydrogen gas formed by the reaction of hydrogen ions with magnesium ribbon
Mg (s) + 2H(aq) = Mg (aq) + H2(g)
