Galvanic Cells

Hi,
When writing the galvanic cell how do you know to put Pt(s)?
Thank you

When there is no solid available for either anode or cathode. A solid is needed as the electrode for the reaction to occur.

To add on to the last post, it's when you don't have a (l)/(s) conductor. This confused me at first because sometimes you'll have a liquid, but still need an inert electrode. This is because the liquid MUST be a conductor (so if it isn't, you still need an inert electrode). I hope you found this helpful!

If a redox reaction is happening between two aqueous, two gaseous, or one aqueous and one gaseous states of matter, an inert electrode must be present such as platinum, which is used in most cases, or graphite. There must be some solid electrode present in both the anode and cathode.

Also,just know that the metals should be transition metals when using them as electrodes.
