  • What is the factor to convert from PO4 to PO4-P? - Hach
    To convert from units of orthophosphate (PO 4 3-) to orthophosphate as phosphorus (PO 4 -P), multiply the value by 0 3261 To convert from orthophosphate as phosphorus (PO 4 -P) to orthophosphate (PO 43-) divide the value by 0 3261 Many Hach spectophotometers and colorimeters give the option to change the chemical form of the reported value This number is a ratio of the atomic mass of the
  • What is the conversion factor from orthophosphate (PO4) to . . . - Hach
    The conversion factor from orthophosphate (PO4) to phosphorus pentoxide (P2O5) is 0 7473 This conversion is based on the molar mass ratio for the two compounds
  • Was ist der Faktor für die Umwandlung von PO4 in PO4-P? - Hach
    Zur Umrechnung von Einheiten von Orthophosphat (PO 43-) in Orthophosphat als Phosphor (PO 4 -P) wird der Wert mit dem Faktor 0,3261 multipliziert Um von Orthophosphat als Phosphor (PO 4 -P) in Orthophosphat (PO 43-) umzuwandeln, dividieren Sie den Wert durch 0,3261 Viele Hach-Spektrophotometer und Kolorimeter bieten die Möglichkeit, die chemische Form des angezeigten Wertes zu ändern
  • Bonding in the phosphate ion - Chemistry Stack Exchange
    Without another base, $\ce {HPO4^2-}$ and $\ce {PO4^3-}$ are also quite unlikely The formal charges are just a book-keeping tool, in the phosphate ion they are delocalised
  • Difference in total phosphate and total phosphorus of biomass
    Orthophosphate, I understand, to be $\ce {PO4^3-}$, the simplest form of phosphate that is readily available for biological use by plants and algae It is an inorganic form of phosphate Total phosphate would include condensed phosphates like polyphosphates and organically bound phosphates

  • Quel est le facteur de conversion de PO4-P à PO4 - Hach
    De nombreux spectrophotomètres et colorimètres Hach offrent la possibilité de modifier la forme chimique de la valeur déclarée Puisque ce nombre est un ratio des masses atomiques des éléments dans la forme chimique, ce calcul ne modifie pas la concentration de phosphore dans l'échantillon ; il ne change que la valeur par rapport aux unités dans laquelle elle est exprimée Par
  • Phosphates Functional Group - Chemistry Stack Exchange
    In my text book it states that a phosphate group is considered to be $\ce {-OPO3^ {2-}}$ However, online it states that phosphate is $\ce {PO4^ {3-}}$ Why do these contradict? Am i confusing phosphat
  • ¿La conversión de una medición de PO4 a PO4-P determina la . . . - Hach
    La conversión de la forma química de los resultados de fósforo de PO4 a PO4-P no da la concentración total de fósforo El fósforo total es la suma de las formas orgánicas e inorgánicas de fosfato y requiere una digestión utilizando calor, ácido y persulfato para convertir fosfatos orgánicos y condensados en ortofosfato para su medición
  • Why are the phosphate ion and hydrogen phosphate not conjugate acid . . .
    The question asks the following, Bronsted-Lowry acid $$\ce {PO4^3- + HNO3 -> NO3- + HPO4^2-}$$ Now, your reasoning is correct $\ce {PO4^3-}$ and $\ce {HPO4^2-}$ are in fact conjugate acid base pairs However, the question doesn't ask for that Rather it asks for the Bronsted-Lowry acid (in this reaction specifically)
