The Total solution for NCERT class 6-12
Hydrochloric acid (HCl) is added to test tube A, while acetic acid (CH3COOH) is added to test tube B. Amount and concentration taken for both the acids are same. In which test tube will the fizzing occur more vigorously and why?
HCl is a strong acidwhereas acetic is a weaker acid. Fizzing occurs because of the production ofthe hydrogen gas obtained due to reaction of the acid on the magnesium ribbon.Since HCl is a very strong acid there is a lot of liberation of hydrogen gasfrom test tube A. therefore, more fizzing take place in test tube A.
