After a student determined the pK values of a H3PO4 by titration, she realized that she had recorded on her data sheet that the concentration of NaOH used in the titration was 0.25 M, but her partner had filled the buret with 0.20 M NaOH. Would you expect the calculated pK values to be correct or incorrect? Explain your reasoning.
