1.	Equal lengths 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 tube B. Amount and concentration of both the acids are same. In which test tube will the fizzing occur more vigorously and why?
Answer» 1. The volatility of acetic acid (CH₃COOH) is more than that of hydrochloric acid. 2. But HCl solution has more strength than acetic acid. 3. Hence magnesium ribbon in test tube A will react more vigorously than in B. 4. So fizzing occurs more vigorously in test tube ‘A’.
