Description
Potassium Carbonate Product Overview
Potassium carbonate (K2CO3) is a white, odorless granular powder. It dissolves very easily in water and gives a strongly alkaline solution. Because it absorbs moisture from the air, it must stay in sealed packaging. Food producers know it as E501(i).
Glass producers use it for optical, crystal and display glass, where potassium gives better clarity and electrical properties than sodium. It is also the starting material for potassium silicate and many other potassium salts. In detergents, it acts as an alkali and builder in liquid soaps and cleaners.
In food, it alkalizes cocoa (dutching) to darken color and soften taste, and it is used in Asian noodles. Industrial gas plants use its hot solutions to remove carbon dioxide from gas streams. When it absorbs CO2 it forms Potassium Hydrogen Carbonate, its milder bicarbonate relative.

Frequently Asked Questions
What is the difference between potassium carbonate and potassium bicarbonate?
Potassium carbonate is a stronger alkali used in glass, chemicals and gas treatment. Potassium bicarbonate is milder and is preferred for baking, beverages and fire extinguishers.
