    Volumetric analysis, also known as titrimetry, is a quantitative analytical technique used to determine the concentration of a substance in a solution. In this technique, a solution of known concentration, called the titrant, is added gradually to a solution of the substance being analyzed until a chemical reaction between the two is complete. The volume of titrant required to complete the reaction is then used to calculate the concentration of the substance being analyzed.

    Volumetric analysis is a popular technique in analytical chemistry because it is relatively simple, fast, and accurate. It can be used to analyze a wide range of substances, from simple inorganic ions to complex organic molecules. Additionally, many different types of reactions can be used in volumetric analysis, making it a versatile technique.

    The most common types of volumetric analysis involve acid-base reactions, oxidation-reduction reactions, and complex formation reactions. In each case, a titrant of known concentration is added to the solution being analyzed until the reaction is complete. The point at which the reaction is complete is often detected using an indicator, which changes color when the reaction is complete.

    Overall, volumetric analysis is an important tool for chemists in a wide range of industries, including pharmaceuticals, food and beverage, and environmental testing.
