I bought Oxalic Acid in an aqueous solution from a hardware store years ago. I need to turn it to powder form for easier storage and other things.
Can I simply evaporate the solution? I seem to notice that evaporating it releases fumes that are similar when one is boiling Acetic Acid. Are there more Oxalic Acid being lost just as it is when boiling Acetic Acid (not distillation)
