Question

When sulphuric acid is poured over zinc, which of the following gases is formed?

A.

Hydrogen

B.

Oxygen

C.

Zinc dioxide

D.

Sulphur dioxide

Correct option is A

The correct answer is (a) Hydrogen.
· When sulphuric acid (H₂SO₄) is poured over zinc (Zn), a chemical reaction occurs, producing hydrogen gas (H₂) and zinc sulfate (ZnSO₄).
· The reaction can be represented as:
Zn+H₂SO₄→ZnSO₄+H₂↑
· This reaction is an example of a single displacement reaction, where zinc displaces hydrogen from sulphuric acid.
Information Booster:
· Hydrogen Gas: Known as a colorless, odorless, and flammable gas, used in various industries, especially in fuel cells and as a reducing agent.
· Sulphuric Acid: A strong acid widely used in laboratories, manufacturing, and industry, especially in fertilizers and battery production.
· Reaction Type: Single displacement reactions involve one element replacing another in a compound.
· Zinc's Reactivity: Zinc is more reactive than hydrogen in the reactivity series, making it capable of displacing hydrogen in acids.
