Sell oxalic acid

Description

There is usually two molecules of crystalized water in it , so it is a kind of transparent, colorless crystals whose structures includeαtype (diamond) andβtype (single inclined crystal), and the melting points of them are **9.5 and **2 celsius degree. The relative dencity of them are 1.**0 and 1.**5. The refractive index is 1.**0. It will sublimate in **0 celsius degree, and more quikly **5, in large quantity in **7 starting to decompose. It is easy to be soluble in ethanol, and can be soluble in water, little in ethyl ether, insoluble in benzene and chloroform.
