Which of the following substances would dissolve iodine?
water
ethanol
polar solvent
vinegar

Ethanol

Explanation:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

The solvent dissolve the solute. The dissolution of solute in to solvent always follow the " like dissolve like " rule of chemistry.

If solvent is made up of polar substance then it dissolve the polar solute. If it is non polar then it can dissolve the non polar substances.

Iodine have covalent iodine-iodine bond which is non polar so iodine would dissolve in ethanol.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
