A concentration cell consists of two Sn/Sn2+ electrodes. The electrolyte in compartment A is 0.30 M Sn(NO3)2. The electrolyte in B is 0.88 M Sn(NO3)2.
Which electrode is the cathode?

A or B?

What is the voltage of the cell? (Answer with two significant figures.)

If we are given a galvanic Cell problem and we are told that the cell consists of one Sn electrode immersed in a 1.00 M solution containing Sn2+ ions, and one Pb electrode immersed in a 1.00 M Pb(NO3)2 solution, how can we determine the cathode/anode? We aren't given any Ecell values.

If the Sn electrode is in Sn2+ solution does that mean it was oxidized?

Why wouldn't the Pb electrode be in an electrolyte solution as well?

If you could please explain I would appreciate it
