The flask was rotated in a thermostat bath until equilibrium was established. The optical densities of different concentration of tetrachloromethane in the aqueous solutions were measured using water as the reference liquid. Duplicate experiments were made and the results averaged. The absorption spectra of tetrachloromethane in aqueous potassium sulfate solutions were determined using a Hilger spectrophotometer.
