Course detail

Laboratory Classes in Analytical Chemistry I

FCH-BCA_ANC1_PAcad. year: 2017/2018

Practical training at analytical reaction of selected ions: cations of alkali metals and alkali earth metals, group of cations precipitating by HCl, by sulphane under acidic conditions, by amonium hydrogensufide, group of anions forming precipitates with baryum (II), anions forming precipitates with and with silver (I).
Practical training of basic quantitative analytical methods: gravimetry, acid-base titrations, compleximetric titrations and redox titrations.

Learning outcomes of the course unit

After students finished this course, they increase their competence as follows:

1. They have overview of analytically and technologically significant reactions of common ions.
2. They extension of knowledge on reactivity and some physical properties of groups of elements/ions.
3. Students be able apply the choice of an important analytical reagents and indicators.
4. Students be introduced with techniques of microscope reactions and small-volume reactions.
5. They will be used precise work in analytical laboratory, preparation of standard solutions and samples.
6. Students will be able to use of basic calculations in gravimerty and volumetry.

Aims

The aim of the first part of laboratory classes on analytical chemistry I, focused on quantitative reactions, is to learn students characteristic reactions of anorganic ions with selected group and selective agents, with visual or basic instrumental detection. The aim of the second part of laboratory classes on analytical chemistry I is introduction of students to problems of qualitative analytical chemistry, mastering of basic analytical methods of gravimetry and volumetry.

Specification of controlled education, way of implementation and compensation for absences

Written entrance tests at the beginning of all exercises checking the students readiness for practical work.
The evaluation of analytical results.
Elaboration of the protocols on a given exercises.
Credit test at the course end.
