Question

Assertion (A): Different metals have different reactivities with water and dilute acids.

Reason (R): Extraction of a metal from its ore depends on its position in the reactivity series.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true, but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Metal extraction from ore is often determined by its reactivity series. Metals with high reactivity, such as sodium and potassium, are often extracted by more reactive methods like electrolysis. Metals with lower reactivity, such as copper and iron, can be extracted through less reactive methods like smelting or carbon reduction.
