character

Vitamin C is white crystal or crystalline powder, odorless, sour taste, and gradually yellowish after long storage. Soluble in water, acidic, slightly soluble in ethanol, insoluble in chloroform or ether. [3]

acidic

Vitamin C has alkene glycol structure in its molecular structure. C2-oh is very weak in acidity (PK2 = 11.57) due to the influence of conjugation effect, while c3-oh is strong in acidity (PK1 = 4.17). Therefore, vitamins are generally monobasic acids, which can act as sodium salts with sodium bicarbonate. [3]

optical rotation

Vitamin C contains two chiral carbon atoms in its molecular structure, so it has optical rotation. According to the legal determination (chp2015 general rule 0621), the specific rotation of the aqueous solution containing 0.10g/ml of this product is + 20.50 ° ~ + 21.50 °.
