Problem
A 10.00 mL sample of 0.500 M phosphoric acid (H₃PO₄) is diluted with water to a total volume of 100.0 mL. A 25.00 mL aliquot of the diluted acid is then titrated with 0.150 M NaOH. What volume of the NaOH solution, in milliliters, is required to reach the second equivalence point of the titration?
(a) 8.3mL
(b) 15.2mL
(c) 16.7mL
(d) 25.0mL
