Question

A voltaic cell is constructed in which the anode is a Co|Co2+ half cell and the cathode is a Sn|Sn2+ 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 the Co|Co2+ electrode the Sn|Sn2+ electrode. In the salt bridge, anions migrate the Co|Co2+ compartment the Sn|Sn2+ compartment.

Answer 1

Answer:

Given,

To give the anode, cathode and net cell reactions

They were given as follows

anode reaction :

Co (s) -------------> Co²⁺ (aq) + 2e-

cathode reaction :

Sn²⁺ (aq) + 2e- -------------------> Sn (s)

net cell reaction :

Co (s) + Sn²⁺ (aq) ----------------> Co²⁺ (aq) + Sn (s)

Here we can say that, In the external circuit electrons migrate from Co|Co²⁺ electrode to Sn|Sn²⁺ electrode.

And In the salt bridge anion migrates from Sn|Sn²⁺compartment to Co|Co²⁺ compartment.
