Potassium tetroxalate dihydrate Usage And Synthesis

Chemical Properties

white crystalline powder or colourless crystals

Uses

A method of utilizing a solution of Oxalic acid potassium salt, dihydrate 99 % to react with calcium in the dentinal fluid forming an insoluble white precipitate of calcium oxalate which occludes the dentinal tubules causing decreased sensitivity, permeability and acid penetration of the dentin.

Uses

Potassium trihydrogen dioxalate dihydrat is used in metal polishing determination of pH. And it is also used in photography, marble grinding, and to remove ink stains.

Purification Methods

Crystallise it from water below 50o. Dry it below 60o at 760mm. [See potassium oxalate above, Beilstein 2 IV 1823.]
