I've just about had it with these salt bridges. It's such an easy concept but there are too many questions about it. I understand that the salt bridge enables the flow of ions for the cathodes and anodes by neutralizing charges, but if you use a different salt bridge (Say zinc nitrate instead of potassium nitrate) would it effect the actual cell potential at all? Although zinc has a lower reducing strength and higher oxidizing strength than potassium, it's still going to neutralize the charges in the solution. Can anyone explain to me if it would or wouldn't effect the cell potential?
