  2. Ammonium phosphomolybdate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_phosphomolybdate

    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.

  3. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    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 ...

  4. Phosphate test - Wikipedia

    en.wikipedia.org/wiki/Phosphate_test

    A range of qualitative and quantitative tests have been developed to detect phosphate ions (PO 3− 4) in solution. Such tests find use in industrial processes, scientific research, and environmental water monitoring .

  5. Natta projection - Wikipedia

    en.wikipedia.org/wiki/Natta_projection

    In a hydrocarbon molecule with all carbon atoms making up the backbone in a tetrahedral molecular geometry, the zigzag backbone is in the paper plane (chemical bonds depicted as solid line segments) with the substituents either sticking out of the paper toward the viewer (chemical bonds depicted as solid wedges) or away from the viewer ...

  6. Vanadium phosphates - Wikipedia

    en.wikipedia.org/wiki/Vanadium_phosphates

    Heating a suspension of vanadium pentoxide and phosphoric acid gives VOPO 4 •2H 2 O, isolated as a bright yellow solid. [4] According to X-ray crystallography, the V(V) centers are octahedral, with long, weak bonds to aquo ligands.

  7. Phosphate phosphite - Wikipedia

    en.wikipedia.org/wiki/Phosphate_phosphite

    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 . Some have third anions.

  8. Ammonium phosphate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_phosphate

    Ammonium phosphate is the inorganic compound with the formula (NH 4) 3 PO 4.It is the ammonium salt of orthophosphoric acid. A related "double salt", (NH 4) 3 PO 4. (NH 4) 2 HPO 4 is also recognized but is impractical to use.

  9. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    [3] [4] This diagram style is an alternative to a sawhorse projection, which views a carbon–carbon bond from an oblique angle, or a wedge-and-dash style, such as a Natta projection. These other styles can indicate the bonding and stereochemistry, but not as much conformational detail.
