Analytical Chemistry B Laboratory 1200-1CHANALBL3
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 NaOH/NaCO3 lub Na2CO3/Na HCO3 using standard HCl solution.Identification of the mixture content. Calculation based on 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. Complexometric determination of the mixture Ca2+ and Mg2+ions.
