Titration is a type of experiment that can be performed to investigate a neutralization reaction. the equivalence point is when all of the acid and base is fully neutralized. a sample of 0.723 m aqueous potassium hydroxide was titrated against a standard solution of hydrochloric acid. what was the volume of the potassium hydroxide solution if 79.1 ml of 1.50 m hydrochloric acid was needed to reach the equivalence point?
