What Is a Primary Standard Titration?

Titration is a common method used to determine the concentration or amount of an unknown substance. Chemicool defines a primary standard titration as an extremely pure reagent that has no waters of hydration and that has a relatively higher molecular weight. In most cases, it is used as a standardization solution.

According to Seattle PI, a primary standard titration exhibits certain characteristics that make it suitable for accurate and reliable assessment of different concentrations without the help of special equipment. A good primary standard titration should be high in purity and low on reactivity with the surrounding environment and air. On the same note, it should have a larger molar mass and easily predictable reactivity. A typical titration, like an indicator, is often used to mark the appearance of an equivalent point between the reactant metal and the primary standard. With the help of a balanced equation, it is possible to determine the molar equivalents of the standard and the reactant chemical, says Seattle PI. In most cases, titrations are used to conduct a thorough analysis of products to be sold. They are used as a product standardization method in many manufacturing firms. This explains why the purity in the standard is supposed to be as high as possible, according to Seattle PI. This is because impurities can skew the reactant chemical’s concentration calculation.
