Výstupy z učení
|
Students acquire skills in the very basic laboratory techniques used in chemical laboratory (weighing, filtration, vacuum filtration, centrifugation, preparing solutions of precise concentrations, acid-base titration with indicator; students also learn several instrumental methods such as potenciometry (pH measuring, usage of potentiometry titration for dissociation constant determination) and spectrophotometry (construction and usage spectrophotometric calibration curve). Students master the fundamentals in preparing final reports on experimental results of laboratory experiments including correct referring to sources of information.
