A) 0.100
B) 0.120
C) 25.0
D) 0.0600
E) 0.240

Quizplus · Accepted Answer

The equivalence point on the titration curve indicates that the moles of acid equal the moles of base added. Using the volume of NaOH at the equivalence point and its concentration, the concentration of the acid can be calculated.
