Basic information

Prerequisites

Course contents (core content level)

The release and absorption of heat in physical-chemical phenomena (calorimetry); vapor-liquid phase equilibrium: distillation of a binary mixture; adsorption on a solid surface: adsorption isotherms; the rate of a chemical reaction and its determination; the conductivity of an aqueous solution and its experimental determination; acid constant and its determination; electrochemistry: primary and secondary cells, electrochemical and thermodynamic quantities; the preparation and behavior of buffer solutions.

The application of spreadsheet computation programmes to present and analyze experimental data; the use of handbooks to find physical-chemical data and values reported in the literature.

Course contents (additional)

The comparison of different adsorption isotherms; the influence of concentration and temperature on the electromotive force of an electrochemical cell; the assessment of the buffer capacity of buffer solutions.

Core content level learning outcomes (knowledge and understanding)

After completion of this course the student understands the following:
? exothermic and endothermic phenomena
? vapour-liquid eqilibrium diagrams
? adsorption isotherms
? the concept of the reaction rate constant and its dependence on temperature
? the principle of the determination of conductivity
? the concept of acid conctant
? the concept of the electromotive force
? the concept of a buffer solution

Core content level learning outcomes (skills)

After completion of this course the student is able to apply spreadsheet computation programmes to present and analyze experimental data. As an example, he can make a linear fit of his data and assess by means of the fit quantities that characterize the phenomenon he has been investigating. In addition, the student is able to find and use data found in physical-chemical handbooks to solve problems. He also knows how to assess qualitatively possible sources of error in experimental work, how to prepare solutions with exact composition and how to use the following equipment:
? calorimeter
? distillation set-up
? refractometer
? spectrophotometer
? conductivity meter
? pH-meter
