* Solutions are homogeneous mixtures where one substance (the solute) is dissolved evenly into another substance (the solvent).
* Suspensions are heterogeneous mixtures where particles of one substance are dispersed but not dissolved in another.
In perfume:
* Fragrance oils (the solute) are dissolved in alcohol (the solvent).
* The fragrance molecules are evenly distributed throughout the alcohol, creating a uniform mixture.
* You can't see the individual fragrance molecules, unlike in a suspension where you can see the particles.
Therefore, because of the uniform distribution of fragrance molecules in alcohol, perfume is considered a solution.
