Study Notes
Mixtures
- A heterogeneous mixture has visibly different parts, like a salad with identifiable ingredients. A homogeneous mixture appears uniform throughout, like salt dissolved in water.
- The key difference between a homogeneous and heterogeneous mixture is the uniformity of appearance.
Examples of Mixtures
- A homogeneous mixture can be classified as a solution such as salt dissolved in water.
- A mixture can be identified as something that combines different substances, unlike a pure substance which is composed of only one type of material and has a fixed composition, like gold.
Pure Substances
- A pure substance is something like a pure element (gold, silver) or a pure compound (water, salt)
- An example of a mixture, as opposed to a pure substance, is a salad, which combines different ingredients (vegetables, etc.) visible to the naked eye.
Mixtures
- A heterogeneous mixture has components that are visibly distinguishable.
- A homogeneous mixture has components that are uniformly distributed and not visibly distinguishable.
