Problem
A student titrates 25.00 mL of a monoprotic acid with 0.100 M NaOH. The actual volume of NaOH required to reach the equivalence point is 24.80 mL, but the student mistakenly adds NaOH until the buret reading shows 25.10 mL before stopping. If the student uses 25.10 mL in the calculation, what percent error will be introduced into the reported molarity of the acid sample?
(a) 0.80%
(b) 12%
(c) 1.2%
(d) −1.2%
