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. ...
Phosphorus comprises 0.1% by mass of the average rock [12] (while, for perspective, its typical concentration in vegetation is 0.03% to 0.2%), [13] and consequently there are quadrillions of tons of phosphorus in Earth's 3×10 19-ton crust, [14] albeit at predominantly lower concentration than the deposits counted as reserves, which are ...
The "backbone" of a polyphosphoric acid molecule is a chain of alternating P and O atoms. Each extra orthophosphoric unit that is condensed adds 1 extra H atom, 1 extra P atom, and 3 extra O atoms. The general formula of a polyphosphoric acid is H n+2 P n O 3n+1 or HO[−P(O)(OH)−O−] n H.
4 Ca 5 (PO 4) 3 F + 18 SiO 2 + 30 C → 3 P 4 + 30 CO + 18 CaSiO 3 + 2 CaF 2 2 Ca 3 (PO 4) 2 + 6 SiO 2 + 10 C → 6 CaSiO 3 + 10 CO + P 4. Side products from the thermal process include ferrophosphorus, a crude form of Fe 2 P, resulting from iron impurities in the mineral precursors. The silicate slag is a useful construction material.
Structural formula of Na 2 HPO 3.The anion has C 3v symmetry.. From the commercial perspective, the most important phosphite salt is basic lead phosphite.Many salts containing the phosphite ion have been investigated structurally, these include sodium phosphite pentahydrate (Na 2 HPO 3 ·5H 2 O).
