| Contents of exercises | Testing the composition of different samples (qualitative). Measurement of control parameters for monitoring the quality of samples (pH, conductivity, oxygen content). Water quality testing (tap, bottled, waste, process): classically volumetric (p and m alkalinity, color, hardness, chloride content), instrumental (potentiometry, selective electrode ion, AAS, IC), pH determination, content of individual cations and anions, conductivity, heavy metals, and other parameters that are indicators of quality. Analysis of the quality of specific materials in the chemical industry: acids, bases, salts, water, gases, alloys, ores, ceramics, composite materials, glass, catalysts, polymers, food, drugs; appropriate techniques. |
