Answer 1

Answer:

Definition • A special type of titremetric procedure involves the formation of precipitates during the course of titration. The titrant react with the analyte forming an insoluble material and the titration continues till the very last amount of analyte is consumed. The first drop of titrant in excess will react with an indicator resulting in a color change and announcing the termination of the titration.

3. • Quantitative precipitation can be used for volumetric determination. • The titration involves precipitation are called precipitation titrations • Two type • Direct • Indirect
