Chemical formula of potassium carbonate: K2CO3
Appearance: Potassium carbonate is either odorless or white powder or granule.
Other names of potassium carbonate: Potassium carbonate, Potash, PotCarb and Pearlash
Potassium carbonate with a molecular weight of 138.205gr / mol is one of the sources of potassium. The potassium element with the symbol of K in the periodic table is considered to be an alkali metal. Its atomic number is 19. Soft silver potassium membrane – silver Be And the seventh element is abundant in the earth’s crust. This element forms about 2.4% of the Earth’s crust’s weight. It is easily oxidized in the air and rapidly reactivates with water. Its reaction with extreme heat is very intense. Pure potash can not be obtained from minerals, but it can be obtained from compounds such as potassium carbonate. Important sources of potassium and potash are sources in California, Germany, New Mexico, Utah and more. At a depth of 3000 feet below the Saskatchewan substrate, there are huge amounts of potash that can be considered as an important source for this element in the future.
Potassium carbonate has a salt taste, which is soluble in water and is not soluble in organic solvents such as water ethanol and acetone. Its vapor pressure is very low and its melting point can not be determined. Potassium carbonate decomposes at high temperatures, and can absorb moisture, which makes the substance look wet and watery. The process of dissolving potassium carbonate in water is a heat-generating process. When dissolved in water, it converts its component parts, potassium cation (+ K) and carbonate anion (-CO32), and displays the alkaline solution.
Potassium carbonate production method:
Potassium and carbonate ions are naturally occurring in nature, so potassium carbonate is compatible with the environment. The presence of carbonate ions increases the pH of the water. Therefore, water containing potassium carbonate should be adjusted to pH before discharging into the environment.
Potassium carbonate is a product that produces a reaction between liquid potassium (KOH) and carbon dioxide.
2KOH + CO2 → K2CO3 + H2O
When potassium is heated to remove impurities in the furnace, potassium carbonate is also made
