Potassium hydrosulfide is an inorganic compound with the formula KSH. This colourless salt consists of the cation K + and the bisulfide anion [SH] −. It is the product of the half-neutralization of hydrogen sulfide with potassium hydroxide. The compound is used in the synthesis of some organosulfur compounds. [1]
Powdered potassium sulfide anhydrous. Potassium sulfide is an inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).
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 ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
If the ligand bonds to the metal center with multiple atoms, the complex is called a chelate. In organic chemistry, there can be more than one chemical compound with the same composition and molecular weight. Generally, these are called isomers. Isomers usually have substantially different chemical properties, and often may be isolated without ...
Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
Clar's rule is widely applied in the fields of chemistry and materials science. For instance, Clar's rule can be used to predict several properties of graphene nanoribbons . [ 10 ] Aromatic π-sextets play an important part in the determination of the ground state of open shell biradical -type structures., [ 4 ] Clar's rule can rationalize the ...
