Understanding Titration Process in Chemical Analysis

Learn how titrations are used to determine the purity of solid chemicals or the concentration of solutions. The process involves a known solution reacting with the sample, using indicators to track the reaction progress. Titration is essential in industries and can be automated with robots for efficiency.

  1. Titrations

  2. Titrations are used for chemical analysis: • to find the purity of a solid chemical • to find the concentration of a solution.

  3. A burette is filled with a solution. This solution will react with the chemical being analysed. The concentration of this solution is known.

  4. A sample of the chemical being analysed is placed in a conical flask. If it is a solid, a balance is used to accurately measure its mass. It is then dissolved in pure water. If the chemical being analysed is a solution, its volume is measured accurately.

  5. An indicator is added to the solution being analysed. This will change colour when the reaction is complete.

  6. The solution in the burette is added to the contents of the flask, while the flask is swirled constantly. Near the end point the solution is added drop by drop.

  7. At the end point the indicator changes colour. The scale on the burette shows the volume of solution that has been added. This is the titre. A calculation gives the purity or concentration of the sample being analysed.

  8. Titrations in industry are often carried out by robots. The robots transfer the solutions, measure volumes and detect the end point.
