Answer :
To determine the precise concentration of a solution whose concentration is uncertain, it is necessary to standardize a NaO H solution.
To obtain an equivalency point and determine the unknown concentration, standardization involves titrating a known volume of N and O H with an acid in a flask.
Because N an O H is hygroscopic in nature—that is, it absorbs water from the air and changes its mass as a result—we cannot determine the precise molarity even when we employ a precise mass balance. The molarity also varies when the mass does. As a result, N an O H standardization is implemented.
