Kool-Aid is classified as a mixture. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. In the case of Kool-Aid, it consists of water, sugar, flavoring agents, food coloring, and sometimes preservatives. Each of these components retains its own properties and can be separated from the mixture.
When you prepare Kool-Aid, you dissolve the powder in water, but the individual ingredients do not change chemically; they simply combine physically. This means that Kool-Aid does not fit the definition of a pure substance or a compound. A pure substance has a uniform and unchanging composition, while a compound is a substance formed when two or more elements chemically bond together. Since Kool-Aid involves several ingredients that can vary and remain unaltered in their properties, it is best categorized as a mixture.
