Question

A voltaic cell is constructed in which the anode is a Co|Co2+ half cell and the cathode is a Cu|Cu2+ half cell. The half-cell compartments are connected by a salt bridge.

(Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.)

The anode reaction is:

The cathode reaction is:

The net cell reaction is:

In the external circuit, electrons migrate _____fromto the Co|Co2+ electrode _____fromto the Cu|Cu2+ electrode.

In the salt bridge, anions migrate _____fromto the Co|Co2+ compartment _____fromto the Cu|Cu2+ compartment.

Explanation / Answer

anode reaction :

Co (s) ---------------------------> Co+2 (aq) + 2 e-

cathode reaction:

Cu+2 (aq) + 2 e- --------------------> Cu (s)

net cell reaction:

Co (s) + Cu+2 (aq)---------------------------> Co+2 (aq) + Cu (s)

In the external circuit, electrons migrate from Co | Co2+ electrode to the Cu|Cu2+ electrode.

In the salt bridge, anions migrate Cu|Cu2+ compartment to the Co|Co2+ compartment
