Assertion (A) Redox couple is the combination of oxidised and reduced form of a substance involved in an oxidation or reduction half cell. Reason (R) In the representation (E_ Fe ³⁺ / Fe ²⁺ ^ ) and (E_ Cu ²⁺ / Cu ^ , Fe ³⁺ / Fe ²⁺ ) and ( Cu ²⁺ / Cu ) are redox couples.

Options

  1. ABoth (A ) and (R ) are true and (R ) is the correct explanation of (A )
  2. BBoth (A ) and (R ) are true but (R ) is not the correct explanation of (A )
  3. C(A ) is true but (R ) is false
  4. DBoth (A ) and (R ) are false

Correct answer

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

Step-by-step solution

Both assertion and reason are true reason is the correct explanation of assertion. Redox couple is the combination of oxidised and reduced form of substance. In the representation (E_ Fe ³⁺ / Fe ²⁺ ^0 ) and (E_ O ²⁺ ^0 / Ou ¹⁻ Fe ³⁺ / Fe ²⁺ ) and ( Cu ²⁺ / Cu ) are redox couples.
