JEE Mains · Chemistry · STD 12 - 2. Electrochemistry
The standard electrode potentials \(\left( {E_{{M^ + }/M}^\circ} \right)\) of four metals \(A, B, C\) and \(D\) are \(-1.2\, V, 0.6\, V, 0.85\, V\) and \(- 0.76\, V\), respectively. The sequence of deposition of metals on applying potential is
- A \(A, C, B, D\)
- B \(B, D, C, A\)
- C \(C, B, D, A\)
- D \(D, A, B, C\)
Answer & Solution
Correct Answer
(C) \(C, B, D, A\)
Step-by-step Solution
Detailed explanation
As the value of reduction potential decreases the reducing power increases i.e. \(\mathop C\limits_{(0.85)} < \mathop B\limits_{(0.6)} < \mathop D\limits_{( - 0.76)} < \mathop A\limits_{( - 1.2)} \)
