Separation+of+Mixtures


 * Properties of Mixtures**
 * Each component in a mixture keeps its own properties
 * 2 types of mixtures
 * homogeneous- the mixture has the same composition throughout
 * heterogeneous- the mixture differs in composure throughout

Ex: salt water can be separated by evaporating the water Oil and water can be separated by letting it settle and after a while it would completely separate
 * Separation of Mixtures**
 * Mixtures can be separated into their components
 * One is able to separate a mixture by taking advantage of the different components properties(ex. magnetism of certain metals)
 * Depending on the type of mixture, different methods can be used to separate each mixture.


 * Separation Methods**

Filtration is used in coffee makers and teabags which filter the grounds and make coffee or tea.
 * Filtration- A mixture of a solid and liquid is poured through some sort of filtering device. The liquid passes through the filter while the solid remains on the filter.
 * When is filtration used?**

Distillation can be used to change saltwater to freshwater by the water evaporating when boiled, and the salt remains. The water then condenses back to liquid.
 * Uses for distillation:**

 * Distillation- When a substance is boiled and the more volatile substance evaporates and the solid material remains at the bottom.The substance evaporated can then revert back to its original state in a pure form.

> This is most commonly used to separate the different pigments in ink.
 * Chromatography**
 * Chromatography- Uses various solids such as paper and starch which are used to separate mixtures. "the writing of colors". This process occurs as chemicals pull certain particles of different sizes and properties up a medium for different lengths based on solubility.
