A. X-sulphuric acid and Y-oxygen gas
B. X-hydrochloric acid and Y-oxygen gas
C. X-sulphuric acid and Y-hydrogen gas
D. X-hydrochloric acid and Y-hydrogen gas [Diksha]
Answer:C
Zinc granules on treating with an acid X, form zinc sulphate (ZnSO4) salt along with the evolution of a gas Y, which burns with a pop sound when brought near to a burning candle. Identify acid X and gas evolved Y.
A. X-sulphuric acid and Y-oxygen gas B. X-hydrochloric acid and Y-oxygen gas C. X-sulphuric acid and Y-hydrogen gas D. X-hydrochloric acid and Y-hydrogen gas [Diksha]
Explanation: When an acid reacts with a metal, hydrogen gas is liberated. In the given reaction, when dilute sulphuric acid reacts with zinc granules, hydrogen gas is liberated and zinc sulphate solution is formed:
