You are titrating 10.00 mL 0.100 M H₃PO₄ with 0.100 M NaOH. At the point where you have added precisely 16.50 mL of the NaOH titrant, which TWO of the following species are the major species (accounting for reactions between the phosphoric acid and sodium hydroxide)? Which is present at higher concentration, which at lower concentration? Classify each of the species as ONE of the following:
N = not a major species
L = major species, lower concentration
H = major species, higher concentration
H⁺
a. N
b. H
c. L
