As we know PPM=mg/Kg, if d=1 so PPM=mg/L
At first we must calculate the densty of ethanol in kg, so when we use 0.5L of ethanol it means :
0.789 kg/L = x kg/0.5L : x=0.394 Kg
For a 100 ppm solution of iodine in 0.5 L of ethanol we have 100=mg I2 /0.394 kg
so mg I2 = 39 mg

What method is used to obtain iodine from a solution of iodine in ethanol?
filtration
Is tincture of iodine a solution?
Yes, it is elemental iodine dissolved in ethanol.
Is iodine and ethanol homogeneous or heterogeneous?
The solution is homogeneous.
Is iodine and water heterogeneous 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.
What will the result of ethanol plus iodine be?
Diatomic Iodine is non-polar, so the reaction will likely be a solution
A leaf was taken from a plant boiled with ethanol and tested with iodine solution what is it tested for?
Starch, I think, because iodine solution is the test for starch.
Is tincture of iodine a solid?
A tincture is a solution; in this case the solvent is ethanol or water.
What is the difference between Iodine bought in a pharmacy and the Iodine stain solution?
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
Does iodine has iron in it?
No. Iodine is itself a chemical element; it contains no other element. If you mean instead tincture of iodine that has no iron in it either. It's a solution of iodine and an iodide in ethanol and water.
