Question

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+))^(ϴ)` and `E_(Cu^(2+)//Cu)^(ϴ), Fe^(3+)//Fe^(2+)` and `Cu^(2+)//Cu` are redox couples
A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true but R is not the correct explanation of A
C. A is true but R is false
D. Both A and R are false

Answer 1

Correct Answer - a
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+))^(ϴ)` and `E_(Cu^(2+)//Cu)^(ϴ), Fe^(3+)//Fe^(2+)` and `Cu^(2+)//Cu` are redox couples.
