Organization of cell diagrams

[Briana Yik 1H]

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

[Iris Bai 2K]

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

[Albert_Luu3K]

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

[Erin Kim 2G]

Yes because you need a solid for electron current change.

[Nandhini_2K]

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

[Danny Zhang 4L]

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

[Aurbal Popal]

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?

[Celine Hoh 2L]

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

[Zubair Ahmed 1L]

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?
