Answer to Question #92816 in General Chemistry for quel

Question

what is meant by the term neautralisation point of a titration?

Answer 1

Titration is the volumetric procedure in analytical chemistry, where the certain amount (volume) of a known substance with an unknown concentration is reacting (drop by drop) with a measured volume of the other substance of a known concentration (titrant). After the reaction is complete, we can calculate the amount of the first substance reacted and its concentration as well. In the case, when we try to determine the concentration of an acid or a base using its reaction with another base or acid, we call this reaction neutralization. Thus, when all titrated acid or base is completely reacted with a base or acid titrant, we call this NEUTRALIZATION POINT. By the way, we indicate this point with using of so-called acid-base indicators (in a classical case).

For example, when we titrate 100 ml of water HCl with a 1M solution of NaOH and at the end we consumed 50 ml of it to reach the neutralization point, then the concentration of HCl solution was equal to 0.5M.
