Question

1.

A voltaic cell is constructed in which the anode is a Mn|Mn²⁺ 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:

(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)

----->

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

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

The net cell reaction is:

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

+

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

------>

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

+

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

In the external circuit, electrons migrate _____(from or to) the Cu|Cu²⁺ electrode _____(from or to) the Mn|Mn²⁺ electrode.

In the salt bridge, anions migrate _____(from or to) the Mn|Mn²⁺ compartment _____(from or to) the Cu|Cu²⁺ compartment.
