Question

Assertion (A): Reactive metals like calcium, magnesium cannot be obtained by reduction.

Reason (R): Reactive metals have a great affinity towards oxygen.

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:

Reactive metals like calcium and magnesium have a great affinity for oxygen, making their oxides very stable and difficult to reduce by common reducing agents. Hence both are true and R correctly explains why electrolytic reduction is used.
