The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl ...
It is a diprotic acid, the hydrogenphosphite ion, HP(O) 2 (OH) − is a weak acid: HP(O) 2 (OH) − → HPO 2− 3 + H + pK a = 6.7. The conjugate base HP(O) 2 (OH) − is called hydrogen phosphite, and the second conjugate base, HPO 2− 3, is the phosphite ion. [8] (Note that the IUPAC recommendations are hydrogen phosphonate and phosphonate ...
Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric (V) acid) is a colorless, odorless phosphorus -containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non- volatile syrupy liquid.
t. e. The Brønsted–Lowry theory (also called proton theory of acids and bases[1]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923. [2][3] The basic concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate ...
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. On the other hand, a conjugate base is what remains after an acid has donated a proton ...
Strong electrolyte. In chemistry, a strong electrolyte is a solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution. Originally, a "strong electrolyte" was defined as a chemical compound that, when in aqueous solution, is a good conductor of electricity.
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. For instance, when an acid dissolves in water, a covalent bond between an electronegative atom and a hydrogen atom is broken by ...
Oxygen gas can enter the hydrogen half-cell and react on the cathode side to form water, which reduces the efficiency of the cell. Gas cross-over from the H 2 to the O 2 evolution side can pose a safety hazard because it can create an explosive gas mixture with >4%mol H 2 .
