Organization of cell diagrams

Postby Briana Yik 1H » Thu Feb 28, 2019 7:13 am

Do you need to put Pt(s) if there is a gas and aqueous molecule in a cell diagram?

Yes i think because there needs to be an actual metal electrode.

Yes, you do! An inert electrode such as Pt is necessary for gas/ion electrode reactions.

Yes because you need a solid for electron current change.

Yes you need add Pt(s) when there's no solid.

You will need it in the absence of solid for either of the half reactions

Also, to add on to her question, you do not need to put Pt on both sides of the cell diagram if there is a solid on the other side, right?

THAT'S RIGHT

Yes, you will need an inert electrode such as platinum when there is a gas and aqueous molecule in the cell diagram because there needs to be a metal present in order for the electrons to be transferred.

What do you do if there's a liquid? I think someone mentioned that Hg(l) is some exception, is that true?
