Question

Equal lengths of mg ribbon are taken in test tubes a and
b. hydrochloric acid is added to test tube
a. while acetic acid is added to test tube
b. in which case the reaction would occur more vigorously and why ? write

Answer 1

Equal lengths of magnesium ribbons are taken in test tubes A and B. Hydrochloric acid (HCl) is added to test tube A, while acetic acid (CH3COOH) is added to test tube B. In which test tube will the fizzing occur more vigorously and why?
Answer: In both the test tubes hydrogen gas is formed. The HCl is strong acid then acetic acid so more hydrogen gas is formed in test tube A which results in vigorous fizzing.

Answer 2

Magnesium metal when reacts with an acid gives off hydrogen gas in the reaction. In test tube A fizzing occurs more vigorously because HCl is stronger acid than acetic acid. Hence, HCl liberates hydrogen gas more vigorously, which causes fizzing more vigorously
