The phosphomolybdate ion, [PMo 12 O 40] 3−. Ammonium phosphomolybdate is the inorganic salt of phosphomolybdic acid with the chemical formula (NH 4 ) 3 PMo 12 O 40 . The salt contains the phosphomolybdate anion, a well known heteropolymetalate of the Keggin structural class.
This template calculates the molecular mass (or molar mass) of a chemical compound. It is designed to be embedded in infoboxes {{ Infobox drug }} and {{ Chembox }} , but it can be used in-line just as well.
A phosphate phosphite is a chemical compound or salt that contains phosphate and phosphite anions (PO 3 3-and PO 4 3-).These are mixed anion compounds or mixed valence compounds. ...
Likewise, tripolyphosphoric acid H 5 P 3 O 10 yields at least five anions [H 5−k P 3 O 10] k−, where k ranges from 1 to 5, including tripolyphosphate [P 3 O 10] 5−. Tetrapolyphosphoric acid H 6 P 4 O 13 yields at least six anions, including tetrapolyphosphate [P 4 O 13] 6−, and so on. Note that each extra phosphoric unit adds one extra ...
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
A lone pair of electrons on an oxygen atom can be donated to a hydrogen ion (proton) or a metal ion in a typical Lewis acid-Lewis base interaction. This has profound significance in biology. For instance, adenosine triphosphate is about 25% protonated in aqueous solution at pH 7. [2] ATP 4− + H + ⇌ ATPH 3−, pK a 6.6
Ammonium phosphate refers to three different chemical compounds, all of which are formed by the reaction of ammonia with phosphoric acid and have the general formula [NH 4] x [H 3−x PO 4], where 1 ≤ x ≤ 3: Ammonium dihydrogenphosphate, [NH 4][H 2 PO 4] Diammonium phosphate, [NH 4] 2 [HPO 4] Ammonium phosphate, [NH 4] 3 [PO 4
It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +. Removal of one proton gives the dihydrogen phosphate ion [H 2 PO 4] − while removal of two protons gives the hydrogen ...
