This tincture is a homogeneous solution.
They are homogeneous. But they are not a mixture, so they are a pure substance
A mixture.
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
It s a mixture is in salt somepercent of iodine solution is added
Iodine is not soluble in water but soluble in organic solvents; sodium chloride is soluble in water. Method 1: dissolving of the mixture in water, filtering, washing of the filter, recovery of iodine from the filter Method 2: dissolving of the mixture in chloroform, filtering, recovery of iodine from the solution by air evaporation at room temperature
