The solution being added is called the titrant, and we say that it solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. used titrate the other A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction…Course Home Courses Ô https://openvellum.ecollege.com/course.html?courseld=16516363&OpenVellumHMAC=6607995b61ef1ebc798fc86a6680d4f.
