Learning Outcomes
After the successful execution of the experiments and the examination the students will be able to succesfully apply:
-the collection of reliable experimental data,
-the use of error analysis,
-the statistical analysis of experimental data,
-the compilation of publication-level laboratory reports
Furthermore, they will be able to operate simple apparatuses and instruments
Course Content (Syllabus)
Viscosity of liquids: Application of Ostwald’s viscosimeter method for the measurement of water viscosity at temperatures between 25 and 50 C. Arrhenious law parameter calculation. Binary vapor-liquid phase diagram: Study of the heterogeneous equilibrium between vapor and liquid phases, in a two component system at atmospheric pressure. Interpretation of deviations from Raoult’s law by means of molecular intreractions. Evaluation of azeotropic composition. Thermocouple calibration study: Calibration of an unknown thermocouple at temperatures between 0 and 420 C by measuring the electromotive forces at the boiling point of liquids, at the liquefaction and meliting points of Sn, Pb and Zn. Thermal analysis: Measurement of the cooling curves of liquid (melt) Pb, Sn and their alloys, using a Ni-NiCr thermocouple. Determination of the freezing points, freezing time, eutectic temperature and composition of the alloys by means of the phase diagram and the break point. Measurement of the surface tension of liquids: Determination of the surface tension coefficient of waterm ethanol and their binary mixtures, by neans of the Traube stalagmometer method. Calculation of related physicochemical properties (molar surface energy, parachor, surface concentration and Szyszkowski constant). Calculation of static and dynamic properties of fluids from Molecular Dynamics Simulation data: Calculation of static, dynamic and thermodynamic properties of pure liquids and their mixtures (i.e., density, isothermal compressibility, diffusion coefficient) from analysis of Molecular Dynamics Simulation data. Utilization of software packages for graphical representation, statistical analysis and error estimation. Constant pressure calorimetry: Calculation of the neutralization enthalpies of solutions of strong and weak acids by an excess of a strong base solution, following the determination of the thermal capacity of the calorimeter and the dilution enthalpy of the base. Study of electrolytic plating: Electrolytic nickel plating on a copper foil. Calculation of all the critical parameters of the electrolytic system, like split voltage, conductivity and metal-over-potential of the electrolutic cell, current ant energy yields of the process and thickness of the nickel plating.
