A) \[Ag,Hg,Cu,Mg\]
B) \[Cu,Hg,Ag\]only
C) \[Ag,Hg,Cu\]only
D) \[Mg,Cu,Hg,Ag\]
Correct Answer: C
Solution :
More the reduction potential, more is the deposition of metals at cathode. Cation having \[{{E}^{0}}\]value less than - 0.83V (reduction potential of \[{{H}_{2}}O\]) will not < deposit from aqueous solution. Hence correct order of A deposition of the metal at the cathode is Ag > Hg > CuYou need to login to perform this action.
