| Hazard Information | Back Directory | 【General Description】
White to very pale yellow crystalline powder with a pleasant sharp acidic taste. Almost odorless. | 【Reactivity Profile】
L-ASCORBIC ACID(50-81-7) 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 . | 【Air & Water Reactions】
May 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. | 【Fire Hazard】
Flash point data for this chemical are not available; however, L-ASCORBIC ACID is probably combustible. |
