Based on my knowledge I think the best candidate for alkali medium (with molarity of higher than 0.1 M) is Hg/HgO electrode.
However, I only have Ag/AgCl reference electrode and Calomel electrode in my lab. I was wondering if SCE can be used as a reference electrode in KOH 1M electrolyte.
I saw some people use it alkali solution, but still some people use Ag/Agcl too! (which is not recommended for alkali solution due to formation of silver oxide).
Thanks for your time
