1.	Equal lengths of magnesium ribbons are taken in test A and B. Hydrochloric acid (HCl) is added to test tube A while acetic acid (CH_(3)COOH) is added to test tube B. In which test tube, will the fizzing occur more vigorously and why ?
Answer» Solution :We KNOW that hydrochloric acid (HCl) is a strong acid and acetric acid `(CH_(3)COOH)` is WEAK acid. Being a strong acid, HCl solution contains a much greater amount of hydrogen ions in it. Due to this , the fizzing will occur more vigorously in test tube A . The fizzing is due to the evolution of `H_2` GAS which is FORMED by the action of acid on the magnesium ribbon.
