stability
1. White translucent crystal or powder. Odorless, sour, citric acid crystallized from a cold solution containing 1 molecule of water, in dry air or heated to 40-50℃ to become anhydrous. Slightly deliquescent in moist air. Becomes soft at 75℃, melts at 100℃, soluble in water and ethanol, soluble in ether. Combustible. Insoluble in chloroform, benzene and other organic solvents. An aqueous solution is acidic. Citric acid is a strong organic acid, which has strong corrosion effect on carbon steel, but not on stainless steel. In case of strong oxidant (such as potassium permanganate) can be oxidized to oxalic acid; When fused with potassium hydroxide, it is decomposed into oxalic acid and acetic acid.
