ml put 25 of the aqueous solution of iodine concentration w / v 1% in suppressing the season, then added his 10ml of Alkrufum, requested the contents of the separating funnel for two minutes, and then separated organic from aqueous layer and then take 5ml from the water layer and Aoert solution Ayari sodium concentration M to thiosulphate 0.1 Vlzim him 1.8ml to reach the end of the calibration, the desired point:
1.ahsb percentage extraction.
2.ahsb concentration of iodine in the organic and aqueous phases after extraction destined for mol / l 3.ahsb coefficient distribution of iodine between the organic and aqueous phases at a temperature of the experiment.
Note: The atomic weight of iodine 1 = 126.9
The mass of iodine is 32.6 g in 1 liter of CCl4 solution
