A) \[Ag,Hg,Cu,Mg\]
B) \[Cu,Hg,Ag\] only
C) \[Ag,Hg,Cu\] only
D) \[Mg,Cu,Hg,Ag\]
Correct Answer: C
Solution :
[c] More the reduction potential, more is the deposition of metals at cathode. Cation having \[E{}^\circ \]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 \[Ag>Hg>Cu\]You need to login to perform this action.
