Using platinum electrodes, the products of the electrolysis of dilute sodium chloride solution are ____________
A. hydrogen and oxygen B. oxygen and chlorine C. sodium amalgam and chlorine D. sodium hydroxide and water
Correct Answer: A
Explanation
If the electrodes are inert, the products of the electrolysis of dilute sodium chloride solution are oxygen at the anode and hydrogen at the cathode.t the anode \(4 \mathrm{OH}^{-} \rightarrow 2 \mathrm{H}_2 \mathrm{O}+\mathrm{O}_2+4 \mathrm{e}^{-}\) \(\frac{\text { At the cathode }}{2 \mathrm{H}^{+}+2 \mathrm{e}^{-} \rightarrow \mathrm{H}_2}\)
