Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
By definition, an organic compound must contain at least one atom of carbon, but this criterion is not generally regarded as sufficient. Indeed, the distinction between organic and inorganic compounds is ultimately a matter of convention, and there are several compounds that have been classified either way, such as: COCl 2 , CSCl 2 , CS(NH 2 ...
Orthocarbonic acid is highly unstable. Calculations show that it decomposes into carbonic acid and water: [2] [3] H 4 CO 4 → H 2 CO 3 + H 2 O. Orthocarbonic acid is one of the group of ortho acids that have the general structure of RC(OH) 3. The term ortho acid is also used to refer to the most hydroxylated acid in a set of oxoacids.
A notable exception is carbonic acid, (H 2 CO 3). [4] Commonly seen as the "fizz" in carbonated beverages, carbonic acid will spontaneously decompose over time into carbon dioxide and water. The reaction is written as: H 2 CO 3 → H 2 O + CO 2. Other carbonates will decompose when heated to produce their corresponding metal oxide and carbon ...
In chemistry and physics, cohesion (from Latin cohaesiō 'cohesion, unity'), also called cohesive attraction or cohesive force, is the action or property of like molecules sticking together, being mutually attractive.
This process is generally represented by the following reaction, where a pressurized dilute solution of carbonic acid in water releases gaseous carbon dioxide at decompression: H 2 CO 3 → H 2 O + CO 2 ↑. In simple terms, it is the result of the chemical reaction occurring in the liquid which produces a gaseous product. [3]
A conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid gives a proton (H +) to a base—in other words, it is a base with a hydrogen ion added to it, as it loses a hydrogen ion in the reverse reaction.
Phase transitions (phase changes) that help describe polymorphism include polymorphic transitions as well as melting and vaporization transitions. According to IUPAC, a polymorphic transition is "A reversible transition of a solid crystalline phase at a certain temperature and pressure (the inversion point) to another phase of the same chemical composition with a different crystal structure."
