0.965g of iodine was shaken with a mixture of 50cm3 trichloromethane and 50cm3 of water in the separating funnel until equilibrium was attained at 25 degrees Celsius. After the layers had settled, 25cm3 of aqeous layers required 4.4cn3 of 0.01M sodium thiosulphate solution using starch indicator. Determine the distribution coefficient of iodine between trichloromethane and water
