Question
A 30.00-mL sample of an unknown H3PO, solution is titrated
with a 0.100 M NAOH solution. The equivalence point is
reached when 26.38 ml of NaOH solution is added. What is the
concentration of the unknown H;PO, solution? The neutraliza-
tion reaction is
H;PO,(aq) + 3 NaOH(aq) → 3 H;O(1) + Na;PO,(ag)
