Description
Photographers' Formulary 10-0241 1LB Overview
Ascorbic Acid is an organic acid with antioxidant properties. The L-enantiomer of ascorbic acid is commonly known as vitamin C.
In 1937 the Nobel Prize for chemistry was awarded to Walter Haworth for his work in determining the structure of ascorbic acid, (It was shared with Paul Karrer, who received his award for work on vitamins), and the prize for Physiology or medicine that year went to Albert Szent-Gyorgyi for his studies of the biological functions of ascorbic acid.
Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions (among others) and as a preservative.
Exposure to oxygen, metals, light and heat destroy ascorbic acid, so it must be stored in dark and cold and not in a metal containment.
