For all concentration cells, they will proceed spontaneously until the concentrations are equal in both compartments.
00:08
So for this concentration cell made up of zinc and zinc 2 plus, we have in the left compartment, zinc concentration, not iron, zinc 2 plus concentration is 1 .16, and on the right hand side, it's 0 .76.
00:28
So in order for the concentrations to become equal, we need to increase the concentration here and decrease the concentration here.
00:40
To increase the concentration, we convert zinc into zinc 2 plus, and to decrease the concentration in the left compartment, we convert zinc 2 plus into zinc, these being the half reactions.
00:56
So the cell potential is going to be equal to e -cell standard, which for concentration cells, is always 0 minus the constant .05916 divided by n, which is 2 moles of electrons, multiplied by the log of the concentration ratio that gives us a positive e -cell...
