Metal cations in aqueous solution can be identified by the colour of the precipitate they form on addition of sodium hydroxide and ammonia; If only a small amount of NaOH is used then normally the metal hydroxide precipitates;. The qualitative analysis is used for the identification of a simple salt or the identification of various cations present in a solution. B. Cations Cations are divided into five groups. A specific reagent for each group is used for their separation from the solution.

Separation schemes result in the identification of each cation. However, confirmatory tests are often added to verify the presence of cations. Confirmatory tests often produce highly colored precipitates or complexes that are characteristic of a given cation. For example, the addition of thiocyanate ion to a solution of Fe 3+ ions produces an intense red solution containing the iron(III.

Background. One common task in analytical chemistry is the identification of the various ions present in a particular sample. The identification of a single cation in solution is a fairly simple and straightforward process, although without a good identification scheme it may require so many experiments as the number of potential cations, if we know at least one specific reaction for each cation. In order to reduce the number of tests required for the identification, it is important to develop a good identification File Size: KB.
