Salt of sorrel

Potassium Hydrogen Oxalate. Potassium acid oxalate [127-95-7], KHC2O4, mol wt 146.15, exists as a monohydrate [6100-03 ]. It is of historical interest because it is the salt of sorrel found in vegetation and the first oxalate isolated.

Potassium Tetroxalate, KOOC—COOH HOOC—COOH 2H2O.— This salt is also known commercially as salt of sorrel. The salts of oxalic acid with the alkali metals are more soluble in water than the free acid itself. Both the salts and the free acid dissolve iron rust and iron inks and are often used for the purpose of removing such substances from cloth. 

Salts Compounds formed by the union of acids and bases, by the action of alkalies upon metals, or by the direct union of elements. The term is often incorporated in the common name of salts used as pharmaceuticals bitter salts, epsom salt, or Seidlitz salt (magnesium sulfate), preparing salt (sodium stannate), Preston s salts (ammonium chloride), Rochelle salt or Seignette s salt (potassium and ammonium tartrate), salt of Mars (ferrous sulfate), salt of Saturn (lead acetate), salt of tartar (potassium carbonate), salt of tin (stannous chloride), salt of wisdom (mercury bichloride and ammonium chloride), sore-throat salt (fused potassium nitrate), vinegar salts (calcium acetate), and vomiting salt (zinc sulfate). The term is also applied to some acids, such as salt of lemon or sour salt (citric acid), salt of sorrel (oxalic acid), and spirit of salt (muriatic acid). ... 

Crystalline colourless solid. Found in many plants, particularly the leaves of the rhubarb plant and in the juice of wood sorrel. Salts of Sorrel, Salts of Lemon.

Monopotassic oxalate—Hydropotassio oxalate—Binoxalate of potash—HKC1O4—1S8—forms transparent, soluble, acid needles. It occurs along with the quadroxalate HKCs04,HaCa04-i-2 Aq, in salt of lemon or salt of sorrel, used in straw bleaching, and for the removal of ink-stains, etc. It closely resembles Epsom salt in appearance, and has been fatally mistaken for it.

He made a detailed investigation of salt of sorrel, which he supposd consisted of a peculiar acid Scheele afterwards proved that this was identical with the acid of sugar (oxalic acid) (see p. 232). Wiegleb thought the acid of sugar (oxalic acid), which he obtained by the action of nitric acid on alcohol, was nitric acid modified by the inflammable principle and he criticised the experiments of Bergman and Scheele on it. 

The quadroxalate of potash was really discovered by F. P. Savary in 1773 by crystallising the binoxalate (salt of sorrel) from dilute sulphuric or nitric acid, but his publication was little known. The salt was later investigated by Anderson. ... 

Oxalic acid is said to be mentioned by F. P. Savary, who knew that salt of sorrel is the potash salt of an acid which he did not isolate. He obtained the neutral oxalate and also, by crystallising from dilute sulphuric or nitric acid, the quadroxalate (rediscovered by Wollaston, see p. 701). 

Bayen reported that (the poisonous) salt of sorrel (potassium binoxalate), which was used to remove ink spots and to make acidulous drinks, very agreeable and healthy (hence perhaps the name salts of lemon still used for it in England), could be manufactured by peasants from cultivated sorrel Rumex acetosd) as was done in Wiirtemberg, ...
