What are the basic requirements of titrimetry? How is gew calculated in case of complexometric and precipitation titrations? Explain with the help of an example for each type
Answers
Answer:
Titrimetry is one of the most widely used analytical techniques. Titrimetry can be classified on the basis of reaction involved in that such as acid-base titrimetry, redox titrimetry, complexometric titrimetry and precipitation titrimetry.
Explanation:
Titrimetry consists of groups of quantitative analysis in which analyte is determined based on its stoichiometric reaction with a reagent with known concentration. The content of analyte is determined based on amount of reagent consumed in the reaction with analyte.
Titration of hydrochloric acid with lead nitrate solution until the formation of precipitate is example of precipitation titrimetry.
Titration of chloride by mercury (II) using urea as an indicator is an example of complexometric titrimetry or chelatometry.
