Question

1. A voltaic cell is constructed in which the anode is a Cd|Cd²⁺ half cell and the cathode is a Co|Co²⁺ 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:

(aq)(s)(l)(g)

(aq)(s)(l)(g)

(aq)(s)(l)(g)

(aq)(s)(l)(g)

The cathode reaction is:

(aq)(s)(l)(g)

(aq)(s)(l)(g)

In the external circuit, electrons migrate _____ the Cd|Cd²⁺ electrode _____ the Co|Co²⁺ electrode.

In the salt bridge, anions migrate _____ the Co|Co²⁺ compartment _____ the Cd|Cd²⁺ compartment.
