For a concentration cell with copper 2 plus and copper metal, the overall reaction will be copper 2 plus with the copper metal, going to copper metal, and copper 2 plus.

So delta e for this reaction under standard conditions, i guess it's not delta, it's just e -cell, will be the standard reduction potential for copper, minus the standard reduction potential.

Potential for copper, copper 2 plus, giving us zero.

So using the nernst equation, e -cell under non -standard conditions will be equal to e -cell standard, which is 0, minus 0 .0 .05916, which we can use at 25 degrees celsius, divided by n, which will be 2, 2 moles of electrons are transferred, multiplied by the log of this concentration, over this concentration, excluding the solids, but which is which? well, for all concentration cells, we need to have a positive e -cell to get a positive with this negative here...
