Why do you need to dry sodium ethandioate (sodium oxalate) at 100 degrees celsius before analysing/titrating?

Are you, by any chance, about to measure the mass of it? Do you know what hygroscopic means?

Yes I will weigh 0.2g then titrate it against KMnO4. No I don't sorry!

Isn't it just to remove any water, as it has to be in anhydrous conditions? I'm probably wrong but that seems like an obvious answer!

Did you google it?

Do you need to know the mass of the salt or the salt plus an unknown mass of water? (since it isn't water of crystallisation, which would be predicable)
