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 …
Oct 16, 2024 · 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.
Jul 12, 2024 · I have recently setup a tank with dry 'Marco rock', ammonia source and bottled bacteria for the first time. In the past I only used live rock to startup my tank. What I am noticing is, nitrates are accumulating as ammonia source is processed to nitrate, phosphate remained 0. After cycling, I adde...
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.
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. …
Muchos de los colorímetros y espectrofotómetros de Hach ofrecen la opción de cambiar la fórmula química del valor indicado. Como este número es una relación de las masas atómicas de los elementos de la fórmula química, este cálculo no cambia la concentración de fósforo en la muestra; solo cambia el valor en relación con las unidades en las que se expresa. Por …
Nov 19, 2015 · What diagramming rules imply that $\ce {PO4^3-}$ should be depicted as my teacher did? Well: none, really. If you are going to stick with the double bond representation, the order of the four structures does not matter as long as they are all there.
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.

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.
