Organic solvents with densities greater than and less than that of the aqueous solution are used to extract the iodine. The aqueous solution of food color is blue. Iodine in water is yellow, and when ...

The solutions used typically included hydrogen peroxide, potassium iodate, and manganese sulfate, which reacted to produce starch-iodine complex changes visible in color. The experiment ...

The technique of extraction is used to separate an aqueous solution of copper (II) chloride and iodine. Organic solvents with densities greater than and less than that of the aqueous solution are used ...
