When we talk about solutions, we’re referring to a homogeneous mixture of two or more substances. In a solution, one substance (the solute) is dissolved in another (the solvent). Let’s examine the options provided:
- Metal Alloys: These are mixtures of two or more metals. While they are uniform in composition, they’re not classified as solutions in the same way liquid mixtures are because they contain solid metals.
- Ice in Water: This is not a solution either, as ice is solid and does not completely dissolve in water. Instead, it remains as a separate phase.
- Sugar in Water: This is a classic example of a solution, where sugar completely dissolves in water to form a homogeneous mixture.
- Vinegar in Water: Vinegar, which is acetic acid diluted in water, also forms a solution when mixed with water.
Considering these options, the one that stands out as not being a true solution is Metal Alloys. Unlike liquid solutions where one component dissolves in another, metal alloys remain distinct solid materials, making them different in classification.
