Question:

In a titration, the equivalence point was reached after adding 24.64 mL of an aqueous NaOH solution to 0.6829 g of potassium hydrogen phthalate (KHP). What is the concentration of the NaOH solution?

Equivalence Point:

The point of an acid base neutralization reaction or any other chemical reaction at which the whole amount of the reactants convert into the products or we can say that the amount of an acid and a base is same is known as equivalence point of the reaction.
