Potassium carbonate is mainly used in the production of soap and glass. [3] Commonly, it can be found as the result of leakage of alkaline batteries. [4] Potassium carbonate is a potassium salt of carbonic acid. This salt consists of potassium cations K + and carbonate anions CO 2− 3, and is therefore an alkali metal carbonate.
It is manufactured by treating an aqueous solution of potassium carbonate or potassium hydroxide with carbon dioxide: [1] K 2 CO 3 + CO 2 + H 2 O → 2 KHCO 3. Decomposition of the bicarbonate occurs between 100 and 120 °C (212 and 248 °F): 2 KHCO 3 → K 2 CO 3 + CO 2 + H 2 O. This reaction is employed to prepare high purity potassium carbonate.

Potassium hydroxide is used for industrial water treatment and is the precursor of potassium carbonate, several forms of potassium phosphate, many other potassic chemicals, and soap manufacturing. Potassium carbonate is used to produce animal feed supplements, cement , fire extinguishers , food products, photographic chemicals , and textiles.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
Chemistry is a physical science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions; it features an extensive vocabulary and a significant amount of jargon. Note: All periodic table references refer to the IUPAC Style of the Periodic Table.
A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3.The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C(−O−) 2.
Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride , KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry. It is an alkali halide salt and occurs naturally as the rare mineral carobbiite .
