Cell potential

How does adding water to a concentration cell affect cell potential? (in the two occasions: anode or cathode)

[Daria Azizad 1K]

It will decrease the concentration. To find out how this affects cell potential, you can plug numbers into E=-RT/nF lnQ with alterations to Q. For instance, if the cathode's concentration decreases, cell potential will increase.

[Anthony Hatashita 4H]

Adding water will decrease the concentration of everyone else, changing the value of Q which changes cell potential.

[Sanjana Borle 2K]

Adding water will dilute a solution, and depending on whether it is added to the anode or cathode, delta G, or work, may also go up or down.

[cassidysong 1K]

How adding water affects cell potential is dependent on which solution it is diluting. If it is diluting the anode solution, then the overall Q is decreased, decreasing the lnQ expression and therefore increasing cell potential since the [-RTlnQ] term is smaller.

[Jacob Villar 2C]

It will dilute the solution, resulting in a change in a Q value due to changes in concentration.

water dilutes the solution.Whether it increases or decreases cell potential depends on the problem
