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 (CH_(3)COOH) is added to test tube B. Amount of concentration taken for both acids are same. In which test tubewill the fizzing occur more vigorously and why ?
Answer» Solution :(a) .A. will show vigorous reaction. (b) It is became `H_(2)SO_(4)` is a STRONG acid. (c ) HYDROGEN gas is liberated. Bring a burning splinter NEAR the gas. It will burn with .Pop. Sound. It shows that the gas liberated is hydrogen. (d) `Mg + H_(2)SO_(4) RARR MgSO_(4) + H_(2) uarr`. `Mg + H_(2)CO_(3) rarr MgCO_(3) + H_(2) uarr` (e)`.A. (H_(2)SO_(4))` will have lower pH. .B. `(H_(2)CO_(3))` will have lower concentration of `H^(+)`.
