Galvanic Cells vs. Concentration Cells
What are the main differences between a galvanic cell and a concentration cell?

Re: Galvanic Cells vs. Concentration Cells
Galvanic cells are solutions with electrodes inserted to measure the electric flow of a redox reaction. Concentration cells are a special type of galvanic cell in which the ions in the anode and cathode are identical, but present at different concentrations.

Re: Galvanic Cells vs. Concentration Cells
Galvanic cells operate on the differing reduction potentials of the solutions on either side that arise due to the fact that they are different compounds while the concentration cells operate on a concentration gradient where the oxidizing and reducing agent are the same compound. In the concentration cell, the reactions occur in order to reach some equilibrium between the two sides of the battery.

Re: Galvanic Cells vs. Concentration Cells
Galvanic cells operate on a reaction between two different species with two different reduction potentials. Concentration cells involve two electrodes of the same species, so their reduction potential is the same. They operate on a concentration gradient.
Re: Galvanic Cells vs. Concentration Cells
everyone else pretty much said it, a galvanic cell consists of two different species in the cathode and anode (like Ag and Zn) while a concentration cell is the same species across (ie both Ag), and is driven by a concentration gradient rather than oxidation/reduction.

Re: Galvanic Cells vs. Concentration Cells
As other people said, the galvanic cell operates with two different compounds and an oxidation/reduction reaction. A concentration cell would be the same compound and flow due to a concentration gradient.
