In this problem, we are told that we have a concentration cell with a silver electrode and ag plus aqueous ions.
00:09
And so therefore, we know that this is the half -reaction that is taking place.
00:15
And in the anode, we have oxidation, so we have ag solid, that silver electrode with an oxidation state of zero, going into ag plus an aqueous solution.
00:25
At the cathode, we have to be undergoing reduction.
00:29
So that means ag plus gains an electron to go to the solid state of the silver electrode.
00:37
And based on the information in the problem, we are given value of the concentration for ag plus ions in the cathode.
00:46
And in part a, we want to determine the same for the anode.
00:51
So we know that this is, these are the two half reactions, the same half reaction taking place since this is a concentration cell.
00:59
However, one is undergoing oxidation and the other one is going reduction.
01:05
So when we add them together, we see that the one electron cancels on each side and solid silver cancels on each side.
01:13
So our overall reaction is ag plus, which is at a concentration of 0 .10 molar, going to ag plus at an unknown concentration that we need to determine in part a.
01:32
And the overall standard cell potential is equal to 0 .00 volts...
