• 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. 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.
