Potassium bicarbonate KHCO

JNH HCO, and potassium bicarbonate [298-14-6] KHCO, are used as well. When used alone, sodium bicarbonate reacts to give products a bitter, soapy flavor. Thus it is always combiaed with a leavening acid. 

Potassium Bicarbonate. Potassium bicarbonate, KHC03, is made by absorption of C02 in a carbonate solution, ie, potassium hydroxide is carbonated to K CC, which in turn is carbonated to KHCO,. The changes of solubility during carbonation are presented in Figure 7. Usually the carbonate is crystallized, washed, and redissolved before carbonation and crystallization of the bicarbonate. The solutions can also be filtered. Thus, the purest carbonate is made by calcining the bicarbonate. Potassium bicarbonate is more stable than NaHC03 at normal temperatures, but KHC03...
