WebSep 20, 2016 · This gives a pH of just over 12. We can calculate this as follows: The number of moles of NaOH added = c ×v = 0.2 × 30 = 6mmol. From the equation the number of moles of PO3− 4 formed must be 1/3 of this. ∴ nPO3− 4 = 6 3 = 2mmol. The total volume of the solution in the flask after titration = 10.00 + 30.00 = 40.00xml.
