Burette in titration
WebTitration: The word titration comes from the Latin word "titulus", which means inscription or title. The French word title means rank. Therefore, Titration means the determination of concentration or rank of a solution with respect to water with a pH of 7. The standard solution is usually added from a graduated vessel called a burette. WebPreparing for titration 100 Points 1 Attempt First you rinsed a pipette with aspirin solution.
