Porous Disc

Postby charlotte_jacobs_4I » Fri Feb 22, 2019 2:43 pm

I am confused on the porous disk that keeps being referred to in class. What is the difference between a porous disc and a salt bridge?

It seems that the main difference is that a salt bridge connects the anode and cathode in separate beakers and allows ions to flow between the solutions while a porous disk does not allow the solutions to mix. However in both cases, ions flow.

Here's a picture that might help. They both allow for electron transfer
