  • Why is (tri-)ammonium phosphate ( (NH4)3PO4) so unstable?
    Ammonium phosphates are solids between 0 and 75°C Because ammonium hydroxide $ (\ce {NH4OH})$ is a much weaker base than the common metal hydroxides, ammonium phosphates are comparatively unstable Both triammonium phosphate ($\ce { (NH4)3PO4}$) and the double salt ($\ce { (NH4)3PO4 2 (NH4)2HPO4}$) are unstable at room temperature and evolve ammonia to form diammonium phosphate Even the
  • inorganic chemistry - The formula of ammonium phosphomolybdate . . .
    It is written in my qualitative chemistry textbook that phosphate could be tested by introducing phosphate, nitric acid and ammonium molybdate which gives (NH4)3H4[P(Mo2O7)6] I found out in the
  • Why does monoammonium phosphate (MAP) have 52% of phosphorus (P₂O₅)?
    The formula of monoammonium phosphate (MAP) is $\\ce{NH4H2PO4}$ Manufacturers say that MAP has 10% of nitrogen (N) and 52% of phosphorus (P) However, its molecular mass is 115 u and the atomic mas
  • What is the precipitate of this reaction of magnesium?
    With $\ce { (NH4)2HPO4}$, $\ce {Mg^2+}$ forms a white, crystalline precipitate of magnesium ammonium phosphate hexahydrate: $$\ce {Mg^2+ + HPO4^2- + NH4^+ + OH- + 5H2O \rightleftharpoons Mg (NH4)PO4 \cdot 6H2O\downarrow}$$ This is a very sensitive test for $\ce {Mg^2+}$; however, calcium, strontium, barium and other heavy metal ions also form precipitates of phosphates under these conditions
  • Yellow precipitate in the presence of ammonium molybdate?
    What reaction could have occurred to cause this? The sink mostly contained diluted $\ce {H2SO4}$ and $\ce {HNO3}$ along with small quantities of $\ce {AgNO3, BaCl2, NH4OH}$, lead acetate and ammonium molybdate All of these would mostly be in small quantities since I had rinsed the sink with water before emptying the test-tube
  • Gravimetric analysis - Chemistry Stack Exchange
    In a gravimetric determination of phosphorus an aqueous solution of dihydrogen phosphate ion is treated with the mixture of ammonium and magnesium ions to precipitate magnesium Ammonium Phosphate
  • Do (some or all) phosphates thermally decompose?
    Hydrogen-phosphates, where the phosphate ion has more complex stoichiometry, can be decomposed by forming denser polyphosphate salts Banach and Makara [1] describe the decomposition of sodium hydrogen-phosphate mixtures, involving several stages and ultimately leaving $\ce {Na5P3O10}$ and subdequently the metaphosphate salt $\ce {NaPO3}$ (in
  • Concentration of ammonium phosphate if dissolved in water
    If $\pu {2 54 mg}$ of ammonium phosphate is dissolved in enough water to make $\pu {300 mL}$ of the solution, what is the molar concentration of the solution? The answer is $\pu {5 68e-5 mol L-1}$
  • analytical chemistry - Source for UV cut-off values of buffers . . .
    When I want to check a $\\mathrm{p}K_\\mathrm{a}$ value I look it up in CRC Handbook Is there such source for UV cut-off values of various buffers? Usually books in chromatography contain tables wit
  • Correct reaction for formation of magnesium pyrophosphate
    The reaction you are referring to is a common salt analysis test for magnesium ion called $\ce {Na2HPO4}$ test From Vogel Qualitative Analysis, 5th ed : $\ce {Na2HPO4}$ test: white crystalline precipitate of magnesium ammonium phosphate $\ce {Mg (NH4)PO4 6H2O}$ in the presence of ammonium chloride (to prevent precipitation of magnesium hydroxide and ammonia solution) The simplified way of
