During electrolysis of molten NaCl, some water is added, What will happen :A. Electrolysis will stop.B. Hydrogen will evolveC. Some amount of caustic soda will be formedD. A fire is likely.

Answer» Correct Answer - B::C::D
(b,c, d) At cathode : `Na^(+)+e^(-) to Na`
At anode : `Cl^(-) to 1//2 Cl_(2)+e^(-)`
On adding water,
`Na+H_(2)O to NaOH+1//2 H_(2)`
The reaction is highly exothermic. As a result, `H_(2)` evolved is likely to catch fire.
