- It does not dissolve in water. Ethanol is soluble in water in all proportions.
- It is soluble in water in all proportions — correct. Yes!
- It dissolves only in tiny amounts. Ethanol is soluble in water in all proportions.
- Tincture iodine. Tincture iodine is a medicine in which ethanol is used as a solvent.
- Vinegar. Vinegar is a solution of acetic acid in water.
