For the electrochemical cell, Ag−∣AgCl∣KCl∣∣AgNO3∣Ag+\mathrm{Ag}^{-}|\mathrm{AgCl}| \mathrm{KCl}|| \mathrm{AgNO}_3 \mid \mathrm{Ag}^{+}, the overall cell reaction isFor the electrochemical cell, Ag^ - |AgCl| KCl|| AgNO_3 Ag^ + , the overall cell reaction is

Options

  1. AAg++KCl⟶AgCl(s)+K+\mathrm{Ag}^{+}+\mathrm{KCl} \longrightarrow \mathrm{AgCl}(\mathrm{s})+\mathrm{K}^{+}
  2. BAg+AgCl⟶2Ag+12Cl2\mathrm{Ag}+\mathrm{AgCl} \longrightarrow 2 \mathrm{Ag}+\frac{1}{2} \mathrm{Cl}_2
  3. CAgCl(s)⟶Ag++Cl−\mathrm{AgCl}(\mathrm{s}) \longrightarrow \mathrm{Ag}^{+}+\mathrm{Cl}^{-}
  4. DAg++Cl−⟶AgCl(s)\mathrm{Ag}^{+}+\mathrm{Cl}^{-} \longrightarrow \mathrm{AgCl}(\mathrm{s})

Correct answer

C. AgCl(s)⟶Ag++Cl−\mathrm{AgCl}(\mathrm{s}) \longrightarrow \mathrm{Ag}^{+}+\mathrm{Cl}^{-}

Step-by-step solution

For the electrochemical cell, Ag−∣AgCl∣KCl∥∣AgNO3∣Ag+\mathrm{Ag}^{-}|\mathrm{AgCl}| \mathrm{KCl} \|\left|\mathrm{AgNO}_3\right| \mathrm{Ag}^{+} The cell reaction is For the electrochemical cell, Ag^ - |AgCl| KCl|| AgNO_3 Ag^ + , the overall cell reaction is
