In the context of fantasy and folklore, a potion is often imagined as a magical concoction with various effects, from healing to granting powers or causing transformations. These potions are typically depicted as liquids with mystical properties.
Scientifically speaking, a solution is a homogeneous mixture of two or more substances. The substances involved in a solution are in a single phase, meaning they are completely mixed at the molecular or ionic level. A solvent, usually a liquid, dissolves the other substances, known as solutes.
In a broader sense, you could metaphorically consider a potion as a type of solution if it is a mixture of different components. For instance, if a "potion" is described as being made by mixing various ingredients, then it could be seen as a solution if the ingredients are uniformly distributed within the liquid.
However, the key distinction lies in the context:
So, while both are mixtures, the term "potion" carries a specific connotation in literature and fantasy that is not applicable in a scientific context.
