What is the reaction occurring at the anode in Down's process for the extraction of sodium?
- A \(4 \mathrm{OH}^{-} \longrightarrow 2 \mathrm{H}_2 \mathrm{O}+\mathrm{O}_2+4 e^{-}\)
- B \(\mathrm{Na}^{+}+e^{-} \longrightarrow \mathrm{Na}\)
- C \(2 \mathrm{Cl}^{-} \longrightarrow \mathrm{Cl}_2+2 e^{-}\)
- D \(\mathrm{NaOH} \longrightarrow \mathrm{Na}^{+}+\mathrm{OH}^{-}\)
Answer & Solution
Correct Answer
(C) \(2 \mathrm{Cl}^{-} \longrightarrow \mathrm{Cl}_2+2 e^{-}\)
Step-by-step Solution
Detailed explanation
In Down's process, at anode, oxidation of \(\mathrm{Cl}^{-}\)into \(\mathrm{Cl}_2\) gas takes place \[ 2 \mathrm{Cl}^{-} \longrightarrow \mathrm{Cl}_2+2 e^{-} \]
