검증된 단계별 안내1
Understand the definition of a solution: A solution is a homogeneous mixture composed of two or more substances where the solute is uniformly distributed within the solvent.
Evaluate each option to see if it fits the definition of a solution:
Liquid mercury is a pure element in liquid form, not a mixture, so it is not a solution.
Pure water is a single substance without any solute dissolved in it, so it is not a solution.
Salt water is a mixture where salt (solute) is dissolved uniformly in water (solvent), making it a homogeneous mixture, which qualifies as a solution.
An oil and water mixture is heterogeneous because oil and water do not mix uniformly, so it is not a solution.
