Which gas is evolved when zinc metal reacts with dilute sulfuric acid?
A. Hydrogen✓ Correct Answer
B. Oxygen
C. Carbon dioxide
D. Nitrogen
💡 Solution & Explanation
Active metals situated above hydrogen in the reactivity series displace hydrogen gas when they react with dilute mineral acids like sulfuric acid. This single displacement reaction yields aqueous zinc sulfate alongside bubbles of flammable hydrogen gas. Such chemical reactions demonstrate the reducing behavior of metals in acidic environments.
