chemical potassium bicarbonate - KHCO₃, molecular weight 100.119. Colorless monoclinic crystal, 2.17g/cm³ density in the air stable, soluble in water, a very weak solution of alkaline, which is insoluble in alcohol. 100 ° CKHCO₃ K₂CO₃ generated decomposition, and CO_{2k H}2O _ / SUB>. Using the kit. KOH to 80% ethanol solution leads to CO₂, can be obtained very pure potassium bicarbonate.
