Precipitation Titration
Precipitation titration is a method based on the formation of a slightly soluble precipitate during the titration process. The procedure involves the following key steps:
Preparation of Solutions:
- Prepare a solution of the analyte (the substance being analyzed) and a standard solution of the titrant (the solution added to react with the analyte).
- The titrant should form an insoluble substance with the analyte.
Titration Process:
- Slowly add the titrant to the analyte solution while stirring until a visible precipitate forms.
- The endpoint is reached when all the analyte has reacted with the titrant, indicated by the formation of a precipitate.
Calculating Analyte Concentration:
- Measure the volume of titrant used during the titration.
- Calculate the concentration of the analyte based on the volume and known concentration of the titrant.
Use of Indicators:
- Indicators like potassium chromate can be used to detect the endpoint by forming colored precipitates.
Types of Titration
Titration is an important process in chemical analysis used to determine the quantity of a sample’s constituent by adding a known proportion of a standard solution. There are several types of titrations based on the nature of the chemical reaction between the sample and the titrant. In this article, we will see what is titration, its types, applications, and more.
