Corrosion and Ion Selective Electrodes

Postby 505095972 » Sun Mar 03, 2019 2:58 pm

The book describes corrosion and ion selective electrodes/glass electrodes In a lot of detail that wasn’t talked about in class. Should we try to understand this in the same detail as in the book or is what we learned in class okay?

If you don't quite grasp the concept, I would suggest reading the book. Other than that I think you should be fine.

Looking at Professor Lavelle's learning outcomes for Electrochemistry (you can access this on the 14B class website), I do not see any explicit emphasis on those types of electrodes so you don't have to really know about it in detail.

However, you should know about inert electrodes (e.g. Platinum, Graphite) because we talked about those in class, and the inert platinum electrode comes up frequently in hw problems involving batteries with non-conducting substances like gases (H2) or half cells with aqueous ions in solution only (e.g. Fe3+/Fe2+).

What did he explicitly talk about for the inert electrodes other than their existence.

The inert electrodes are written in cell potential diagrams when either electrode does not have a metal.
