AIPMT PRELIMS 2001 Chemistry Electrode Potentials MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Stand electrode potential are Fe²⁺/Fe E° = – 0.44 Fe³⁺/Fe²⁺ E° = 0.77 If Fe²⁺, Fe³⁺ and Fe block be kept together, then :-
A
Fe³⁺ increases
B
Fe³⁺ decreases
C
Fe²⁺ remains unchanged
D
Fe²⁺ decreases
Correct Answer
Option B
Detailed Explanation
The potential difference between Fe²⁺/Fe and Fe³⁺/Fe²⁺ indicates that Fe³⁺ will be reduced to Fe²⁺, increasing the concentration of Fe²⁺.
