If a small amount of iodine is dissolved in ethanol, which classification is correct?
Answer and explanation
Correct answer: Non-aqueous solution
The governing concept is that an aqueous solution specifically has water as its solvent. Here iodine is the solute and ethanol is the solvent; because ethanol is not water, the mixture is classified as a non-aqueous solution. The small amount of iodine affects quantity, not the classification. It is not gaseous because ethanol is liquid, and it is not a solid solution because the solvent is not solid. Thus A is correct.
