Q20 / 90 · JEE Main 2014 (09 Apr Online) · Chemistry
The standard electrode potentials of four metals and are , and , respectively. The sequence of deposition of metals on applying potential is
- A
- B
- Correct answerC
- D
Solution
In complete cation electrolysis at cathode, the species having higher reduction potential is preferably reduced at cathode
Hence,
will be the preference of deposition of these metals on competing.
Hence, the correct answer is option: 'C'.
