MHT CET 2024 Chemistry question
What is the decreasing order of deposition of metal on electrode if standard reduction potential 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
Answer: (A)
Solution
When several metal ions are present, the ion with the higher (more positive) standard reduction potential is reduced first, so its metal is deposited first at the cathode. Order of : ( V) ( V)
