How many milliliters of 0.0839 M NaOH are required to titrate 25.0 mL of 0.0990 M HBr to the equivalence point?
A)29.5
B)0.332
C)4.57
D)0.208
E)21.2

Question

Quizplus · Accepted Answer

The correct answer is A because the number of moles of NaOH required to titrate the HBr is equal to the number of moles of HBr present in the solution. The number of moles of HBr is equal to the molarity of the HBr solution multiplied by the volume of the solution in liters. The number of moles of NaOH required to titrate the HBr is equal to the molarity of the NaOH solution multiplied by the volume of the solution in liters. The volume of the NaOH solution required to titrate the HBr is equal to the number of moles of NaOH required to titrate the HBr divided by the molarity of the NaOH solution.
