Question

Identify the correct reaction from the options given below for the electrolysis of $CuC{l}_2$.

• A. At anode: $2C{l}^{-}\to C{l}_2\left(g\right)+2e^{-}$
• B. At anode: $C{u}^{2+}+2e^{-}\to Cu\left(s\right)$
• C. At cathode: $2C{l}^{-}\to C{l}_2\left(g\right)+2e^{-}$
• D. At cathode: $2C{l}^{-}\to C{l}_2\left(g\right)+4e^{-}$

Answer 1

The correct option is A At anode: $2C{l}^{-}\to C{l}_2\left(g\right)+2e^{-}$

The process of chemical change taking place in an electrolyte by passing electricity is known as electrolysis. Following reaction takes place during the electrolysis of $CuC{l}_2$:

At anode: $2C{l}^{-}\to C{l}_2\left(g\right)+2e^{-}$ (Oxidation)

At cathode: $C{u}^{2+}+2e^{-}\to Cu\left(s\right)$ (Reduction)
