Study Methodology Of Analytical Group I Cations

Abstract

The article analyses the necessary measures to be taken to modernize chemistry courses at universities. The basic principles of analysis and study of properties, the significance and application of K+, Na+,NH4 + cations of the analytical group I have been discussed.

The teaching process is carried out in the following 6 stages: The relation between the atom structure and the properties of the elements, their compounds; Their biological role; Use of metal cations of analytical group I in medicine; Particular identification reactions; Test task - analysis process of group I cations; Representation of the results of the analytical group particular reactions and the analysis of the mixture by the given schemes.

In order to achieve the goal, the student is involved in research-examination processes, is informed about the essence of research, determines the stages of research and deeply understands its results, at the same time explores its meaning, is given opportunity to understand, comprehend and interpret the information learned, develops skills in practical application of methods and strategies, in identification of risk factors related to experimental work, in selection and compilation of different types and complexity appropriate to the goal set.

In the process of teaching analytical chemistry, such a methodical approach is important for effective management of practical work and ensuring a safe environment.
