What is the decreasing order of deposition of metal on electrode if standard reduction potentials are given as - Ag ⁺ | Ag =0.80 ~V , Cu ²⁺ | Cu =0.337 ~V Sn ²⁺ | Sn =-0.136 ~V , Cd ²⁺ | Cd =-0.403 ~V
Options
- AAg Cu Sn Cd
- BCu Sn Cd Ag
- CSn Cd Ag Cu
- DCd Sn Cu Ag
Correct answer
A. Ag Cu Sn Cd
Step-by-step solution
Higher the standard reduction potential ( E ^ ) value, greater the tendency of the species to accept electrons and undergo reduction. Order of E _ red ^0: Ag ⁺ Cu ²⁺ Sn ²⁺ Cd ²⁺ Decreasing order of deposition of metal on electrode is as follows: Ag Cu Sn Cd .
