Back titration is used in complexometric titration when the analyte reacts slowly with the titrant or when a direct titration is not feasible due to interference from other substances. By adding an excess of a known reagent to react with the analyte, followed by titration with another reagent to determine the excess, the concentration of the analyte can be accurately calculated.

Difference between precipitation titration and complexometric titration?
In precipitation titration, the formation of a solid precipitate is used to determine the endpoint of the titration, while in complexometric titration, a complex formation reaction is used to determine the endpoint. Precipitation titration is often used for specific ion determinations, while complexometric titration is used for determining metal ions by forming stable complexes with titrant.
What are complexometric titration method?
Complexometric titration is a type of volumetric analysis used to determine the concentration of metal ions in a solution by forming complexes with a specific reagent. In this method, a chelating agent is typically used to form a stable complex with the metal ion, and the endpoint of the titration is usually determined using a colorimetric indicator or a pH meter. This technique is commonly employed in the analysis of a variety of metal ions in solution.
What is the principle of complexometric titration?
Complexometric titration is a type of volumetric titration that involves the formation of a complex between a metal ion and a complexing agent. The endpoint of the titration is determined by a color change or a change in a physical property caused by the complex formation. It is commonly used to determine metal ions in solution.
What is the displacement titration?
Displacement titration is a type of titration where the analyte can displace a reagent from a complex it forms, leading to a change in a measurable property. This displacement can be used to calculate the concentration of the analyte. It is commonly used in complexometric titrations in chemistry.
What are the buffers used in complexometric titration?
Buffers commonly used in complexometric titrations include ammonium acetate-acetic acid, ammonia-ammonium chloride, and potassium hydrogen phthalate. These buffers help maintain a relatively constant pH during the titration process, ensuring accurate and precise results.

What is the role of mordant black indicator in complexometric titration?
Mordant black indicators are used in complexometric titrations to visually signal the endpoint of the titration. They form colored complexes with metal ions, resulting in a visible color change when all the metal ions have reacted with the titrant. This color change helps in determining the endpoint of the titration accurately.
Why do we only use calcium carbonate in complexometric titration?
Calcium carbonate is commonly used in complexometric titration because it forms stable complexes with a variety of metal ions, making it useful for determining the concentration of those metal ions in a sample. This complex formation helps in the accurate and precise determination of metal ions through titration.
What is role of buffer solution in complexometric titration?
In complexometric titration, a buffer solution is used to maintain a constant pH throughout the titration process. This helps to ensure that the conditions are optimal for the formation of the metal-complex, leading to more accurate and reliable results. The buffer also helps to minimize the effect of changes in pH on the endpoint of the titration.
What are the method of titration?
The methods of titration include acid-base titration, redox titration, and complexometric titration. Acid-base titration involves the reaction between an acid and a base to determine the concentration of one of the reactants. Redox titration involves oxidation-reduction reactions to determine the concentration of a substance. Complexometric titration involves the formation of a complex between a metal ion and a complexing agent to determine the concentration of the metal ion.
