Mixtures and Pure Substances by Mind Map: Mixtures and Pure Substances

1. Examples of Mixtures and Pure Substances

1.1. Some examples of Pure Substances are water, diamond, salt, sugar, and tin.

1.2. Some examples of mixtures is mud, water and food coloring, water and oil, and pretty much any substance that is combined with another.

2. Pure Substances

2.1. Pure substances can be elements and/or compounds. Compounds are a thing that is composed of two or more separate elements. An element is each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter.

3. Mixtures

3.1. Mixtures are substances that is mixed with another substance and is not pure. Mixtures can be a combination of multiple things, and it does not have to be just two substances.

4. Solutions

4.1. Solutions are a liquid mixture in which the smaller component (or the solute) is uniformly distributed within the larger component (or the solvent). A solution is also a compound.

5. Mixtures vs. Pure Substances

5.1. A mixture is the product of the random distribution of one substance through another without any chemical reaction, as distinct from a compound. Mixtures are a combination of multiple things and can be separated and broken down more.

5.2. A pure substance is s a material that has a constant composition and has consistent properties throughout the sample. Pure substances are homogeneous, meaning they have a uniform appearance throughout the sample and can not be pulled apart or broken down anymore.

6. Homogeneous vs. Heterogeneous Mixtures

6.1. A heterogeneous mixture is simply any mixture that is not uniform in composition. The parts in the mixture are capable of being pulled apart from each other.

6.2. A homogeneous mixture has the same uniform appearance and composition throughout. They are commonly referred to as solutions.

7. Separating mixtures

7.1. Some tools used to separate mixtures are filters, evaporation, distillation, magnetism, and using a centrifuge.
