L(+)-Ascorbic acid is white or slightly yellowish crystalline or crystalline powder, odorless, with a sour taste.
Melting point of 190 ~ 192 ℃, polarimetric alpha D20 = + 21 ° ~ + 22 °.
Soluble in water, soluble in ethanol, insoluble in chloroform, ether and benzene.
The Ph value of 5% aqueous solution was 2.2 ~ 2.5.
It is stable in dry air, and its aqueous solution is unstable,
especially it is quickly oxidized in neutral or alkaline solution. When exposed to light,
heat, copper, iron and other metal ions, the oxidation will be accelerated.
