Does anyone know the stability of aquaous l-ascorbic acid for storage?
Say, storage at 25
o
C and the solution is saturated.
Do adding of EDTA Calcium Disodium help to stabilise it?

One day for a standardized solution; seven days for an approximate solution, eg, "5% ascorbate". EDTA will prevent metal-catalyzed oxidation; make sure it doesn't interfere with the intended use.
