potassium metabisulfite as substitute for sodium (meta)bisulfite
The title says it all: Can potassium metabisulfite be used as substitute for sodium (meta)bisulfite for isolation of aldehydes and ketones? Or is it
not practical for solubility/stability reasons or whatever?
This post makes me think it can:

I think solubility may be an issue, the potassium salt is pretty low. If you already have the potassium metabisulfite you could always try a run with
a couple if cc of acetone.
