A) \[Na,{{O}_{2}}\]
B) \[{{H}_{2}},{{O}_{2}}\]
C) \[Na-Hg,C{{l}_{2}}\]
D) \[C{{l}_{2}},Na-Hg\]
Correct Answer: C
Solution :
[c] : A brine solution is electrolysed using a mercury cathode and a carbon anode. At cathode : \[{{N}^{+}}+{{e}^{-}}\xrightarrow[{}]{Hg}\]Na-amalgam At anode : \[C{{l}^{-}}\xrightarrow[{}]{{}}\frac{1}{2}C{{l}_{2}}+{{e}^{-}}\]
