Week 5-6: Organic Reagents in Inorganic Analysis

Reagent is generally known as the substance used in a chemical reaction to detect, measure, examine or produce other substances because of the reactions it causes.

They are mainly used in analysis and synthesis

Organic reagents are used for detection or estimation of inorganic or organic substances by micro or macro analysis.

The requirements for the organic reagent are dictated by the analytical method used

•Should complex Forming agents (Form complexes with metals ion to be determined/identified.

•Should  form colored solutions or precipitates with metal ions

•Should  have Large Surface area

•Should stable complexes with metal ions

•Should have high molecular weight to give large amount of precipitates
