Why is iodine soluble in oil and not water?
Why is iodine soluble in oil and not water? The reason the iodine molecules leave water to dissolve in oil is due to how polarity affects solubility. Oil is non-polar; electrons in molecules of this substance are distributed evenly. Iodine is also a non-polar molecule therefore it is more soluble in oil; “like dissolves like”. […]
