Polyphosphoric acid ph
WebSep 7, 2024 · For example polyphosphoric acids are useful reagents that have more phosphorous content that phosphoric acid. It would be ambiguous to state the concentration as $115\%\ \ce{H3PO4}$ (what does 115% mean) so instead procedures are reported in terms of $\ce{P2O5}$ concentration with the balance assumed to be water … WebAt each equivalence point, the pH is the average of the pKa values above and below. At the last equivalence point (the end point), the pH is determined by the Kb of the conjugate base of the weakest acid. The example below should illustrate these points. We will plot the titration of 100 mL of 0.10 M phosphoric acid with 1.0 M NaOH. H3PO4 + H2O ...
