Product Description

POTASSIUM TETRABORATE TETRAHYDRATE CAS 12045-78-2

Potassium tetraborate is also called the boric acid potassium (potassium borate). White crystal. Anhydrous density 1.74g/cm3. Soluble in water, slightly soluble in alcohol, aqueous solution is alkaline. It is made by reaction of boric acid and potassium carbonate, by filtration, cooling crystallization, centrifugal separation and drying. Used in the manufacture of disinfectants and as a standard substance for acid titration in chemical analysis.
