The Physical chemistry exercises in practical level complements the subject Chemistry II – Physical Chemistry. Within the frame of the subject students are getting acquainted with the following topics of physical chemistry measurements:
• Measurement of the density of the liquid and solid samples and determination of the surface tension.
• Viscosity measurements of the liquids and its dependency on the temperature.
• Determination of the partial molar volumes.
• Determination of the heat capacity of the solid samples.
• Phase equilibrium in three components system.
• Extraction, determination of the distribution ratio.
• Determination of the molecular weight using ebulioscopic and cryoscopic technique.
• Conductivity measurement of the electrolytes, its dependency on electrolyte concentration and temperature.
•Determination of the dissociation constant for week acids based on the measurement of the conductivity. Evaluation of the solubility product.
• Determination of the molar absorption coefficient. Evaluation of the band gap energy of the semiconductors in powder form.
• Rate of the chemical reactions, evaluation of the specific rate constant of the pseudo-first order chemical reaction.
