Conductor as an Electrode

Postby Jennifer_Lam_1A » Sun Feb 05, 2017 9:11 pm

Hi everyone! On page 48 of the course reader, it says to use Pt as the inert conductor as the electrode to transfer the electrons. I was wondering where they got the Pt from. Is it just a random element to transfer the electrons?

It is a relatively inert metal that has a high conductivity, and is well suited for the role of transferring electrons. It is also widely used for this purpose.

Yes but one thing that also strikes me is why specifically Platinum, and not gold or copper? Would it not make sense that a lot of wires and communication vectors use Cu as a material? Just thought about this since my iphone and laptop cable seems to Cu inside!

It doesn't ALWAYS have to be platinum, the course reader just used Pt as an example.
