Change in Ecell

Postby Brittney Hun 2C » Wed Mar 11, 2020 3:54 pm

Will Ecell increase if the size of the anode metal is increased? Does the metal have anything to do with it? And will Ecell increase if a substance is added to the cathode side?

No, if you increase the mass of the solid it doesn't affect Ecell (I'm pretty sure this was one of the questions on test two).

I do not think that changing the size of the anode metal (if you mean the actual electrode) will have an affect on Ecell. The identity of the metal does affect Ecell which is why you use specific reduction/oxidation equations. It depends on what is added to the cathode side, but if it is a pH neutral salt, nothing with happen.

Since the electrode is a solid it is not factored into the equilibrium constant and therefore increasing or decreasing its mass will not affect the Ecell.

Increasing the size of the metal does not change the cell potential

Increasing the size of the metal does not cause a change in Ecell.
