Define cerimetry titration and it's application
Answers
Answer:
Cerimetry or cerimetric titration, also known as cerate oximetry, is a method of volumetric chemical analysis developed by Ion Atanasiu.Since cerimetry is linked to the Fe3+/Fe2+ redox pair, it can be used for analyses of nonstoichiometric levels that either oxidize Fe2+ or reduce Fe3+.
Answer:
Cerimetry titration is a type of redox titration that involves the use of cerium(IV) ions as the oxidizing agent and a reducing agent as the analyte.
Explaination:
During the titration, a known amount of the cerium(IV) ions is added to the solution containing the analyte until all the reducing agent is oxidized.
Cerimetry titration has various applications in analytical chemistry, including:
- Quantitative analysis of reducing agents: Cerimetry titration can be used to determine the concentration of reducing agents, such as ascorbic acid, iron(II) ions, and oxalic acid, in a sample.
- Determination of the purity of certain compounds: Cerimetry titration can be used to determine the purity of some organic compounds, such as aldehydes and ketones, which can be oxidized by cerium(IV) ions.
- Analysis of trace amounts of elements: Cerimetry titration can also be used to determine the concentration of trace elements, such as iron and copper, in a sample.
