Problem
During a titration, 25.00 mL of a monoprotic acid solution that actually has a concentration of 0.0500 M is titrated with 0.100 M NaOH. The chosen indicator changes color at 12.20 mL of added NaOH, although stoichiometric neutralization requires 12.50 mL. Using 12.20 mL in the calculation, the student reports the acid concentration. Calculate the percent error in the reported concentration and state whether it is an overestimate or an underestimate.
