A) 1 F
B) 2.33 F
C) 2 F
D) 1.33 F
Correct Answer: C
Solution :
\[CuS{{O}_{4}}\rightleftharpoons C{{u}^{2+}}+SO_{4}^{2-}\] At cathode: \[C{{u}^{2+}}(aq)+2{{e}^{-}}\xrightarrow{{}}Cu(s)\] At anode \[2{{H}_{2}}O(l)\xrightarrow{{}}{{O}_{2}}(g)+4{{H}^{+}}(aq)+4{{e}^{-}}\] Thus, for the production of one mole of copper from copper sulphate 2F of electricity is required (because involve 2 electrons).
