### Ion-Selective Electrodes/finding pH

Posted:

**Wed Mar 15, 2017 11:42 pm**Hi,

I'm still a little bit confused on what ion selective electrodes are and how they relate to the Nernst equation.

I'm also not sure how the pH of a solution may be determined from the Nernst equation.

Basically, the top half of page 54 in the course reader, the section titled "Applications of e- transfer reactions" is not making sense to me.

If anyone could provide any sort of clarification on either of these two topics I would greatly appreciate it.

Thank you!
