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 )

Respuesta :

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

Explanation:

The given chemical cell follows:

[tex]Co(s)|Co^{2+}(aq.,0.0155M)||Ag^{+}(aq,3.50M)|Ag(s)[/tex]

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

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

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

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

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