-
The decomposition reaction of potassium bicarbonate is 2 KHCO3 --> K2CO3 + H2O + CO2 (potassium bicarbonate --> potassium carbonate + water + carbon dioxide). This decomposition occurs at temperatures above 100 degrees Celsius.
Molar Mass
The molar mass of potassium bicarbonate is 100.12 grams per mole (39.10 g/mol (potassium) + 1.008 g/mol (hydrogen) + 12.01 g/mol (carbon) + 3 x 16.00 g/mol (oxygen) = 100.12).
Appearance
Potassium bicarbonate appears as a white granular powder.
Decomposition of Potassium Carbonate
Continued heating of the potassium carbonate produced in the decomposition of potassium bicarbonate will produce potassium oxide.
Synthesis of Potassium Bicarbonate
Potassium bicarbonate is synthesized through the reaction of potassium carbonate with water and carbon dioxide.
Use
Potassium bicarbonate is generally considered safe and has applications in the food industry, pharmaceuticals, agriculture, and in fire extinguishers.
