H₂PO₄ + OH → HPO₄²⁻ + H₂O
11.5 ml 0.4932 M NaOH titrant required to obtain the equivalence point.
Determine the theoretical equivalent weight of H₂PO₄⁻ in the titration reaction. Using the theoretical equivalent weight of H₂PO₄⁻ and the equivalents of H⁺ transferred in the titration reaction, calculate the amount (in grams) of H₂PO₄⁻.
