Sodium hypophosphite (NaPO 2 H 2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO 2 H 2 ·H 2 O. It is a solid at room temperature, appearing as odorless white crystals. It is soluble in water, and easily absorbs moisture from the air.
An amphiprotic molecule (or ion) can either donate or accept a proton, thus acting either as an acid or a base. Water, amino acids, hydrogencarbonate ion (or bicarbonate ion) HCO − 3, dihydrogen phosphate ion H 2 PO − 4, and hydrogensulfate ion (or bisulfate ion) HSO − 4 are common examples of amphiprotic species. Since they can donate a ...
A typical derivative is the salt [NH 4][HP(O) 2 OH]. [7] [6] Many related salts are known, e.g., RbHPHO 3, CsHPHO 3, TlHPHO 3. These salts are prepared by treating phosphorous acid with the metal carbonate. These compounds contain a layer polymeric anion consisting of HPO 3 tetrahedra linked by hydrogen bonds. These layers are interleaved by ...
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 sodium salt of phosphoric acid. It consists of sodium cations (Na +) and dihydrogen phosphate anions (H 2 PO − 4). One of many sodium phosphates, it is a common industrial chemical. The salt exists in an anhydrous form, as well as monohydrate and dihydrate (NaH 2 PO 4 ·H 2 O and NaH 2 PO 4 ·2H 2 O respectively). [1]
Transition metal phosphate complexes are coordination complexes with one or more phosphate ligands. Phosphate binds to metals through one, two, three, or all four oxygen atoms. The bidentate coordination mode is common. The second and third pK a 's of phosphoric acid, pK a2 and pK a3, are 7.2 and 12.37, respectively.
Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.
4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO 4. The term also refers to the trivalent functional group OP(O-) 3 in such esters. Phosphates may contain sulfur in place of one or more oxygen atoms (thiophosphates and organothiophosphates).
