Problem
A student titrates 25.00 mL of a monoprotic acid with 0.100 M NaOH. Because the indicator changes color 0.30 mL after the true equivalence point, the student records 24.80 mL as the volume required to reach the endpoint.
Calculate the percent relative error in the acid’s calculated molarity that results from using the endpoint volume instead of the true equivalence volume. (Express the error to two significant figures.)
