Potassium Bicarbonate

Potassium bicarbonate is an inorganic compound that is used to manufacturing the soap and glass. It is called as the pearl ash and carbonate potash. It is a hygroscopic and odourless and same as the alkaline. It is insoluble in acetone and readily soluble in water. The systematic IUPAC name is known as potassium hydrogencarbonate. The chemical or molecular formula of potassium bicarbonate is KHCO3 . The other names is potassium acid carbonate.

Structural Formula

This is the structural formula of the potassium bicarbonate:

Potassium Bicarbonate

Chemical Formula

The chemical formula of the potassium bicarbonate is KHCO3.

Preparation Method

When the potassium carbonate is reacted with the carbon dioxide and water,  it gives the results of potassium bicarbonate.

K2C03 + CO2 + H20 → 2 KHCO3

It can be substitute for baking soda and ingredient low sodium baking powders. It should be an expensive and nontoxic base. it has decomposed at the high level temperatures such as 100 and 120C.
