The practice is aimed to understand and learn the analytical chemistry methods solving in practice some characteristic analytical problems; skills acquisition of precise laboratory work; the development of independent decision-making skills; practice of processing the measured data and preparing reports; Problem solving in connection with analytical procedures and their theoretical bases; develop basic material recognition routine.
8. Course Outline:
Topics Covered:
The common reactions of inorganic ions in aqueous solutions, qualitative identification.
Preparation of samples for the analysis. Volumetric methods: preparation of standard solutions, standardization; acid-base titrations; methods based on complex formation and precipitation; gravimetry; redox titrations: measurements with permanganate, chromate, bromate and cerium(IV) standard solutions, iodometry; methods for the analysis of natural waters. Determination of two or more components in the presence of each other. Titrations in non-aqueous solutions. Separations by distillation, ion exchange, precipitation.

10. Requirements:
10.1. Course Work:
Only students registered in the Neptun system can attend the lectures.
Prerequisites for completion of course/laboratory (in addition to those listed in „ELTE Organizational and Operational Regulations”) include:
-compliance with requirements and regulations (signature required);
- submission of report of each measurement on time, succeeded completion of at least 90% of the measurements (documented by accepted reports)
-the average performance of the qualitative identification of the unknowns and the exam must be at least 50%
-the homeworks must be accepted
-at least 7 of the short tests written at the beginning of each lab day must be more than 50%
-the success of each test must be more than 50% (after improvement), answer the basic questions included in the test more than 75% required to check the test.
10.2. Exam Period
If all of the requirements for the practical part are fulfilled but one of the test is less than 50% (but more than 10%), retake examination is available.
