Ascorbic Acid
« on: November 25, 2005, 10:31:23 AM »
I am interested in the chemical reaction of ascorbic acid with chlorine. Also need to know if a water solution of ascorbic acid is stable or does it break down over time?

Aqueous solutions of ascorbic acid are not stable.  Generally, if I need a solution of ascorbic acid for an assay, I will store it at 4 C for no more than 3 days.  Solid ascorbic acid can be stored at room temp, but it should be stored in a brown bottle to prevent light from degrading it.
