Potassium bicarbonate is very rarely found in its natural form, the mineral called kalicinite. ==Chemistry== Decomposition of the bicarbonate occurs between 100 °C and 120 °C: :2 KHCO3 → K2CO3 + CO2 + H2O It is manufactured by reversing the above: reaction of potassium carbonate with carbon dioxide and water. :K2CO3 + CO2 + H2O → 2 KHCO3 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「potassium bicarbonate」の詳細全文を読む スポンサード リンク
