  • organic chemistry - Dehydration of carboxylic acids using P2O5 . . .
    The hydrogen bonding stabilise the molecule, enabling the organic chain to form additional bonds by dispersion forces Also dehydration of carboxylic acids with phosphorus pentoxide (P2O5) yields acid anhydrides,because it strong dehydrated anhydride ;P2O5 itself reacts with water molecules to form phosphoric acid
  • P2O5 concentration % based on a 75% Phosphoric Acid Solution
    If I want to obtain a P2O5 concentration of 4,7 % in my final solution, what % of Phoshoric Acid Solution at 75% I need to put in? My guess is about 8,7 % of 75% Phoshoric Acid Solution, is it that correct?
  • How to convert P2O5 concentration to H3PO4 concentration?
    1 $\ce {P2O5}$ content is useful as it is the phosphorous content that a scientist often cares about when using phosphoric acids This might seem silly given that as you pointed out anything from $0-70\% \ \ce {P2O5}$ could just be expressed as a percentage of $\ce {H3PO4}$ but there are times when a higher $\ce {P2O5}$ concentration is desired
  • Is the proper formula for phosphorus oxide(V) P4O10 or P2O5?
    Note that empirical formula and molecular formula are different Ambiguous use of "formula", which can mean two different things, causes your confusion P2O5 is the empirical formula and P4O10 is the molecular formula
  • Why is phosphorus (v) oxides molecular formula P4O10 and not P2O5
    I understand that the name derives from the empirical formula; however, I do not understand why it does not exist as $\\ce{P2O5}$ Is there a compound that exists with this as its molecular formula?
  • Reactions of P2O5 and P4O10 with sulfuric acid [closed]
    $$\ce {H2SO4 + P2O5 -> SO3 + 2HPO3}$$ $$\ce {6H2SO4 + P4O10 -> 6SO3 + 4H3PO4 }$$ Since it is a dehydration reaction the oxidation states of sulphur and phosphorous would be the same in reactant and product, this is true for both the reactions Are the both Products correct $\ce {HPO3}$ and $\ce {H3PO4}$ correct? If yes what I am missing?
  • Why is phosphorous pentoxide a dehydrating agent?
    Phosphorus pentoxide can dehydrate nitric acid to form its anhydride, dinitrogen pentoxide $$\ce {2HNO3 -> [P2O5] [- H2O] N2O5}$$ Why dinitrogen pentoxide is not used as a dehydrating agent? My take on this is that hydrolysis of dinitrogen pentoxide is not that exothermic as compared to hydroysis of phosphorus pentoxide

  • Consider the reaction 2H3PO4---- gt;P2O5+3H2O Using the information in the . . .
    Consider the reaction 2H3PO4---->P2O5+3H2O Using the information in the following table, Question: Consider the reaction: 2 H 3 P O 4 → P 2 O 5 + 3 H 2 O Using the information in the following table, calculate the average rate of formation of P 2 O 5 between 10 0 and 40 0 s Express your answer with the appropriate units
  • Mechanism of carboxylic acid and amide dehydration with phosphorus . . .
    Dehydration of carboxylic acids with phosphorus pentoxide ($\ce {P2O5}$) yields acid anhydrides, and in a similar reaction, amides dehydrated with phosphorus pentoxide yield cyanides Can an arrow p
