| 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. |
