Concentration Cells

Postby eduardomorales5 » Thu Feb 27, 2020 7:20 pm

Whats the difference between a concentration cell and a galvanic cell? Does one of them do more work than the other cell?

A concentration cell is an electrolytic cell that is comprised of two half-cells with the same electrodes, but differing in concentrations. The only work done from a concentration cell occurs from a difference in concentration

both concentration and galvanic cells are batteries in which the redox reaction has a positive voltage, however;

concentration cells have the same chemical species (with different concentrations) while galvanic cells have different chemical species

Galvanic and Voltaic cells are both sensitive to changes in [R] and [P], so they can be made with the same components at different concentrations. Concentration cells consist of the same species on both sides but differ in concentrations, like the example from lecture with Ag at 1M and 0.1M

Both galvanic and concentration cells have a positive voltage, but the difference between both is that in concentration cells contain the same chemical species but in different concentrations, the difference in concentration drives movement of electrons, and the voltage tends to be very low. In galvanic cells the chemical species are different.

Is there different equations to use?

A concentration cell has different concentrations.
