Usage And Synthesis:

Chemical Properties: White crystals General DescriptionWhite to very pale yellow crystalline powder with a pleasant sharp acidic taste. Almost odorless. Air & Water ReactionsMay be sensitive to prolonged exposure to air and light. Sensitive to moisture. Soluble in water. Aqueous solutions are oxidized by air in a reaction that is accelerated by alkalis, iron and copper. The rate depends on the pH and on oxygen concentration. Also subject to degradation under anaerobic conditions. Reactivity ProfileL(+)-Ascorbic acid is a lactone. Reacts as a relatively strong reducing agent and decolorizes many dyes. Forms stable metal salts. Incompatible with oxidizers, dyes, alkalis, iron and copper. Also incompatible with ferric salts and salts of heavy metals, particularly copper, zinc and manganese . Fire HazardFlash point data for L(+)-Ascorbic acid are not available; however, L(+)-Ascorbic acid is probably combustible. L(+)-Ascorbic acid
