A 31.5 mL aliquot of HNO₃(aq) of unknown concentration was titrated with 0.0134 M NaOH (aq). It took 23.9 mL of the base to reach the endpoint of the titration. The concentration (M) of the acid was . A) 0.0102 B) 0.0051 C) 1.02 D) 0.227 E) 0.0204

Question

Quizplus · Accepted Answer

The correct answer is A because the concentration of the acid can be calculated using the formula:M1V1 = M2V2where M1 is the concentration of the acid, V1 is the volume of the acid, M2 is the concentration of the base, and V2 is the volume of the base.Substituting the given values into the formula, we get:M1 * 31.5 mL = 0.0134 M * 23.9 mLSolving for M1, we get:M1 = 0.0102 M
