Oxalic Acid - LoveToKnow 1911 |
 | | Oxalic acid is very poisonous, and by reason of its great similarity in appearance to Epsom salts, it has been very frequently mistaken for this substance with, in many cases, fatal results. |
 | | Beside the ordinary acid and neutral salts, a series of salts called quadroxalates is known, these being salts containing one molecule of acid salt, in combination with one molecule of acid, one of the most common being "salt of sorrel," KHC 2 0 4. |
 | | Ethyl oxalate, (C0.0C2H5)2, prepared by boiling anhydrous oxalic acid with absolute alcohol, is a colourless liquid which boils at 186° C. Methyl oxalate (CO. 00H3)2, which is prepared in a similar manner, is a solid melting at 54° C. It is used in the preparation of pure methyl alcohol. |
