Chemical formula K2CO3 is an anhydrous white solid which dissolves from incandescent degree of decomposition. This chemical which is soluble up to 100% in water is insoluble in alcohol.
Production and Reactions
It is obtained by passing carbon dioxide from potassium hydroxide. Potassium carbonate K2CO3; roasting of potassium bioxalate is obtained in pure form; Washing the wood ashes and roasting the residue obtained by evaporation of the concentrated solution; can be obtained.
It can be obtained from the processing of raw product and retort residue obtained by burning beet molasses. Potassium carbonate can also be obtained by the Leblanc method, such as sodium carbonate.
TV tube, laboratory glass, optical glass, used in the kitchen is used as an additive in glass making.
It is used in pharmaceutical industry with potassium carbonate potassium citrate. It is also used as rocket fuel and drug adhesive. It is also used as a buffer in wine production as electrolytes in many experiments with cold fusions.
This sector is widely used in the drying of grapes. In addition, chocolate production, beer fermentation, livestock feed industry is used.
It is used during the absorption of gases in the solution prepared using potassium carbonate.
In this sector, it is used as an additive by taking advantage of its high solubility.
It is used in titanium dioxide flit.
