This is a titration of a triprotic acid. For example H3PO4, phosphoric acid. The titration curve pH vs. volume shows only two equivalence points. Its titrated with NaOH. Being a triprotic and having 3 acid dissociation constants Ka1, Ka2, Ka3 one would expect to see three equivalence points.
Why does it only show two equivalence points?
What mass of F2 is needed to produce 205 g of PF3 if the reaction has a 79.3% yield?
Identify the mass spectral (MS) peaks you would expect for 4-Heptanone (M+ and m/z for all fragments). Just FYI, the professor said
Total heat evolved by the reaction by adding the heats required to raise both the solution and the calorimeter to the maximum temperature. 5). Heat evolved per mole of Mg 6) Change in enthalpy for the following specific reaction. Be sure to indica..
