* Solutions are homogeneous mixtures of two or more substances.
* Pure water consists of only one substance: H₂O molecules.
Think of it this way:
* Solution: Like saltwater, where salt (solute) is dissolved in water (solvent).
* Pure water: Like a single ingredient, there's nothing else mixed in.
While pure water is often used as a solvent to create solutions, it itself is not a solution.
