Experiments cover a number of topics: solubility and activity coefficient heat of solution; three component phase diagram; phase diagram of a binary liquid vapor system; kinetics of the persulphate iodide reaction (effect of ionic strength or reaction rate); kinetics of the hydrolysis of methyl acetate (first order reaction); kinetics of the hydrolysis of hydrazones (specific acid catalysis); stability of aspirin; viscosity; absorption isotherms; electrolytic conduction; Clasius-claypron equation; partition coefficient, and determination of formation constant of I2 complex.
