Last update: doc. RNDr. Iva Zusková, CSc. (15.03.2019)
Principles of fundamental physico-chemical phenomena are demonstrated in ten exercises. Basic thermodynamic, kinetic and electrochemical characteristics, as equilibrium constants, rate constant, buffer capacity etc., are determinated. Required data are obtained by means of chemical analysis (e.g. titration, extraction) and by common instrumental methods (UV-VIS spectrophotometry, polarography, potentiometry, conductometry, electrolysis, viscosimetry). Emphasis is given on appropriate interpretation of measured data and their mathematical and statistical evaluation.

Podmínky pro získání zápočtu:

- splnit vstupní požadavky  - test na 60% 

- absolvovat všechny úlohy,

- řádně vést laboratorní deník,

- odevzdat bezchybné protokoly ke všem úlohám (Za protokoly je možné získat či ztratit body, které v součtu s body ze závěrečného testu rozhodují o udělení zápočtu. Za každý bezchybně vypracovaný protokol student/ka získá 1 bod (bonusový bod!), bude-li protokol vrácen k opravě, nezíská žádný bod. Bude-li protokol opětovně vrácen, protože např. nebyly opraveny všechny vytknuté chyby, ztrácí 1 bod, a to i opakovaně, dokud nebude protokol v pořádku.),

-  získat alespoň 30 bodů ze závěrečného testu (max. 50 bodů) a protokolů (závěrečný test lze opakovat, maximálně však 2x).
