Short description:

The aim of laboratory is to present classic methods of quantitative analysis applied in practice in many laboratories among other connected with environmental protection. Individually performed titrations based on: acid-base, precipitation, reduction and oxidation, complex formation reactions. The manual experience acquired is essential in laboratory work for every chemist.

Laboratory is accurately connected with laboratory „Instrumental Analysis” performed during IV semester.

Full description:

All students have to perform preliminary exercises:

• Bases of laboratory technique: reliable measurement of liquide volume, heating of solutions, precipitation, filtering and precipitate washing and ignition, titration technique, forms of laboratory notebook.

• Calibration of volumetric glassware: flask and pipet

• Manipulation associated with weighting - weighting of Na2CO3

Students implementing level B have to perform following exercises:

• Preparation of 0.2 mol/l HCl and its standaridization using weighted Na2CO3. Determination of NaOH.

• pH-metric titrimetric determination of CO3 2- i HCO3- using standard HCl solution. Calculation of CO3 2- i HCO3- content using titration curves.

Preparation of 0.05 mol/l AgNO3 solution using dried salt. Titration of Cl- ions by Mohr method.

• Indirect manganometric determination of calcium. Precipitation of CaC2O4 and its dissolution in H2SO4 solution. Titration of C2O4 2-ions with standard solution of KMnO4.

• Preparation of 0.05 mol/l EDTA solution and its standardization using ZnO. Volumetric determination of the mixture Ca2+ and Mg2+ions.
