Potassium carbonate is a potassium salt, which is a dipotassium salt of carbonic acid. It acts as a catalyst, fertilizer and flame retardant. Carbonates and potassium salts. Hydrogen is the lightest element. Under standard conditions, hydrogen is a gas composed of diatomic molecules of formula H2.

Potassium carbonate (K2CO3) is a white salt that is water-soluble (insoluble in ethanol) and forms a strongly alkaline solution. It can be produced as a product of the endothermic reaction of potassium hydroxide and carbon dioxide. It provides a great ability to tát absorb moisture.

Hydrogen is the lightest element. Under standard conditions, hydrogen is a gas composed of diatomic molecules of formula H2. It is colourless, odourless, tasteless, non-toxic and highly flammable. Hydrogen is the most prevalent chemical in the universe, making up roughly 75% of all regular compounds.

Potassium carbonate is an inorganic compound with the chemical formula K2CO3. It is a white salt that dissolves in water. It deliquescence and often appears as a moist or moist solid. Soaps and glasses are the most common uses for potassium carbonate.

Potassium carbonate is the main component of potash and more refined pearl ash, or the salt of potassium bitartrate. Pearl ash was made by burning potash in a kiln to tát remove impurities. Pearl ash was the fine white powder that remained. The first patent issued by the US Patent Office was granted to tát Samuel Hopkins in 1790 for an improved process for producing potash and pearl ash. 

 In North America in the late 18th century, pearl ash was used as a leavening agent for quick bread before baking powder was developed.


 Hydrogen (H) is a colorless, odorless, tasteless, flammable gaseous substance and is the simplest thành viên of the chemical element family. A hydrogen atom has a nucleus consisting of protons that carry a unit of positive charge. Also, this nucleus is associated with an electron that carries a unit of negative charge. Under normal conditions, hydrogen gas is a loose assembly of hydrogen molecules, each composed of a pair of atoms, a diatomic molecule, and H2. The earliest known and important chemistry of hydrogen is that it burns with oxygen to tát khuông water, H2O. In fact, the name hydrogen comes from the Greek word for “water maker.”

Hydrogen is the most abundant element in the universe (three times as rich as helium, the second most abundant element), but it makes up only about 0.14 weight percent of the Earth’s crust. However, it has been found in large quantities as part of the ocean, pack ice, rivers, lakes, and water in the atmosphere. Hydrogen is present in all animal and plant tissues, not just petroleum, as a component of countless carbon compounds. It is often said that there are more known carbon compounds than vãn any other element, but in reality, hydrogen is present in almost all carbon compounds and all other elements (except some noble gases). increase. There may be a large number of hydrogen compounds.

Chemical reactivity of Potassium Carbonate with hydrogen:

 To determine the unbiased rate of decomposition of KHCO3, a slowly increasing constant temperature TGA method was used on small, finely ground samples. Such reactions provide a new porous and reactive adsorbent for harmful and / or malodorous gases. Bicarbonate begins to tát decompose at 364K and reaches a maximum reaction rate of 5.73 × 10-41 / s at 421.9K. The Arrhenius-type relationship is created by the integral method using the Schromilch function. The activation energy is as large as 141.3 kJ / mol, and the reaction order is 1.145. The pore volume (0.2309 cm3 / g) produced by calcination ranges from 403 to tát 503 K and is temperature independent, but the average pore size and particle size increase with increasing temperature. The graphs presented allow us to tát conveniently predict the conditions for achieving near-complete conversion of bicarbonate and minimizing unwanted sintering of the resulting carbonate. 

The inorganic compound potassium bicarbonate (IUPAC name: potassium hydrogen carbonate, often known as potassium carbonate) has the chemical formula KHCO3. It’s a solid white colour.

Structure of Potassium Carbonate: 

Potassium salt, which is a dipotassium salt of carbonic acid.


Potassium carbonate reacts with hydrochloric acid. This series shows the addition of solid potassium carbonate (K2CO3) to tát a beaker containing 0.5 M hydrochloric acid. The reaction of HCl + K2CO3→ KCl + CO2 + H2O produces carbon dioxide gas bubbles. This is an example of a carboxylic acid reaction, which is itself a double exchange reaction followed by a decomposition reaction.

Hydrochloric acid and potassium carbonate react according to tát the following balanced chemical equations to tát khuông liquid water, carbon dioxide gas, and aqueous potassium chloride. 2 HCl (aq) + K2CO3(aq) → H2O (l) + CO2 (g) + 2 KCl (aq) A total of 15.3 mL of gas is collected on the water. The atmospheric pressure is 776 mmHg and the water temperature is 30.0 ° C. The vapor pressure of water at 30.0 ° C is 31.86 mmHg.
