Gravimetric Analysis

An example of a gravimetric analysis is the determination of chloride in a compound. In order to do a gravimetric analysis, a cation must be found that forms an insoluble compound with chloride. This compound must also be pure and easily filtered. The solubility rules indicate that Ag +, Pb 2+, and Hg 2 2+ form insoluble chlorides.

Copper(I) complexes. Forming copper(I) complexes (other than the one with water as a ligand) also stabalises the copper(I) oxidation state. For example, both [Cu(NH 3) 2] + and [CuCl 2]-are copper(I) complexes which don't disproportionate. The chlorine-containing complex is formed if copper(I) oxide is dissolved in concentrated hydrochloric acid.

Qualitative Analysis Identifying Anions and Cations

Qualitative analysis is used to identify and separate cations and anions in a sample substance. Unlike quantitative analysis, which seeks to determine the quantity or amount of sample, qualitative analysis is a descriptive form of analysis.In an educational setting, the concentrations of the ions to be identified are approximately 0.01 M in an aqueous solution.
