On what basis are cations separated into groups

Hello friend here is your answer.
In this system cations are classified into five groups on thebasis of their behaviour against some reagents, called group-reagents. By the systematic use of these reagents one can decide about the presence or absence ofgroups of cations, and can alsoseparate these groups for further examination.
i hope it will help you

Hey friend ur answer is
========================================================================================================================
If a sample contains only a single cation and anion, their identification is a fairly simple and straightforward process, although to distinguish between two cations (or anions) that have similar chemical properties is not easy and in this instance additional confirmatory tests are required. The detection of a particular ion in a sample that contains several ions is somewhat more difficult, because the presence of the other ions may interfere with the test. This problem can be circumvented by precipitating, thereby removing, the disturbing ions from solution prior to testing for the particular ion. The successful analysis of a mixture containing large number of ions centres upon the systematic separation of the ions into groups containing only a few ion. It is much simpler task to work with 2 or 3 ions than with 10 or more
