Qualitative analysis is mainly concerned with the detection and identification of constituents of an inorganic compound or a mixture of substances. The systematic analysis of cations is an integral part of the salt analysis (or systematic qualitative analysis). The inorganic mixture given for analysis is made from such components, which, on dissolving in water, split up into two types of charged particles, one carrying a negative charge called anion or acidic radical and the other carrying a positive charge known as cation or basic radical.

To conduct a qualitative analysis of an inorganic mixture, several experiments are performed to detect the presence of acidic and basic radicals present in it, known as tests. The cations are classified into five groups based on their behaviour against some reagents. By the systematic use of these group reagents, we can decide about the presence or absence of a group of cations and can also separate these groups for further examination.
