The distribution of iodine between carbon tetrachloride and water at 25 has been studied as a function of the total iodine concentration (10_1 to 10-6 M)\the pH of the aqueous phase (1.0 to 7.0); and the time of mixing. Both tracer techniques and spectrophotometric methods …

The partition coefficient (R) is the ratios of the volume fractions of iodine in water to the volume fraction of iodine in air above water at equilibrium. The partition coefficient is a mathematical formula for predicting iodine content in earth's atmosphere from a specific concentration in water. In a combination of two immiscible phases, the distribution coefficient is a measure of the concentrations of both ionization and unionized species of a chemical.
