    Systematic Analysis of Cations - Stages of Experiment

    Cation – A cation is an ion carrying positive charge which is attracted to the cathode during the process of electrolysis. A systematic analysis of cations is performed to separate and recognise cations which are commonly known from a mixture of salt. This experiment helps analyse the properties of cations and understand the concept of precipitation and formation of the

F r o m Ce to Sm the increase in Rf is possibly caused by the lanthanide contraction, this being confirmed by the behaviour on resins. The selectivity of the cation decreases as the atomic number increases and hence Rf increases with the atomic number
