Which of the following reactions cannot be A base for electrochemical cell?

View answer and explanation

Correct option: D

\mathrm{KMn}{\mathrm{O}_4} + \mathrm{FeS}{\mathrm{O}_4} + {\mathrm{H}_2}\mathrm{S}{\mathrm{O}_4} \to {\mathrm{K}_2}\mathrm{S}{\mathrm{O}_4} + \mathrm{F}{\mathrm{e}_2}{(\mathrm{S}{\mathrm{O}_4})_3} + \mathrm{MnS}{\mathrm{O}_4} + {\mathrm{H}_2}\mathrm{O}

Option C is correct because

\mathrm{AgN}{\mathrm{O}_3} + \mathrm{NaCl} \to \mathrm{AgCl} \downarrow + \mathrm{NaN}{\mathrm{O}_2}

is a precipitation reaction, not a redox reaction, and therefore cannot be a basis for an electrochemical cell.
