Question

Write the net cell equation for this electrochemical cell. Phases are optional. Do not include the concentrations. Co ( s ) ∣ ∣ Co 2 + ( aq , 0.0155 M ) ∥ ∥ Ag + ( aq , 3.50 M ) ∣ ∣ Ag ( s )

Answer 1

Answer: The net cell equation for the given electrochemical cell is given below.

Explanation:

The given chemical cell follows:

$Co(s)|Co^{2+}(aq.,0.0155M)||Ag^{+}(aq,3.50M)|Ag(s)$

Oxidation half reaction: $Co(s)\rightarrow Co^{2+}(aq,0.0155M)+2e^-$

Reduction half reaction: $Ag^{+}(aq,3.50M)+e^-\rightarrow Ag(s)$       ( × 2)

Net cell reaction: $Co+2Ag^{+}(aq,3.50M)\rightarrow Co^{2+}(aq,0.0155M)+2Ag(s)$

Oxidation reaction occurs at anode and reduction reaction occurs at cathode.

Hence, the net cell equation for the given electrochemical cell is given above.
