Stability
1. It is relatively stable in dry air, impure and many natural products can be oxidized by air and light. Its aqueous solution is unstable, and it can be oxidized to Dehydroascorbic acid quickly, especially in neutral or alkaline solutions. When exposed to light, heat, iron, copper and other metal ions, it will accelerate oxidation, and can form stable metal salts. As a relatively strong reducing agent, the color darkens after storage and turns to varying degrees of light yellow. Median lethal dose (mice, intravenous) LC50: 518mg/kg
2. It is prone to deterioration when exposed to air and heat, and is prone to oxidation and failure in alkaline solutions. Under air conditions, it rapidly deteriorates in aqueous solution and is a strong reducing agent
3. Exists in flue gas.
4. Widely distributed in animals and plants. Stable to air during drying. The aqueous solution is rapidly oxidized by air.
