Titration is a common method of determining the amount or concentration of an unknown substance.
The method is easy to use if the quantitative relationship between two reacting solutions is known. Titrations are routinely used in industry to analyze products to be sold. Many manufacturers are under strict standards of quality control because their products are sold for public consumption. The products to be tested include antacid tablets, vinegar, fruit juice, and household ammonia. A standard solution is one in which the concentration is known accurately.
