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?

The volume of the potassium hydroxide solution was 164.1 mL

Explanation:

In the equivalence point of a titration between an acid an a base, the moles of H⁺ are equal to the moles of OH⁻.

In the case of potassium hydroxide (KOH) and hydrochloric acid (HCl), an equation that represents the equivalence point would be:

Using that equation and the data given in the problem, we can calculate the volume of potassium hydroxide:

the answer would be a
