Mixtures : Vocabulary Part I

1) Mixture: a physical combination of two or more substances that do not form new substances (Salt water).

2) Suspension: is a mixture whose particles settle and separate within a few hours.

3) Solution: is a mixture whose particles are the size of atoms or molecules (not visible to the human eye).

4) Solvent: does the dissolving in a solution (water in salt water).

5) Solute: gets dissolved in a solution (salt in salt water).

6) Solubility: it is the greatest amount of solute that a

given amount of solvent can dissolve.

7) Filtration: separates substances that have particles of

different sizes.

8) Homogenous: solutions that have the same makeup

throughout (Salt water).

9) Heterogeneous: separate particles are big enough to

see (Salad Dressing).

Mixtures : Main Ideas1) What is a Mixture? (pg. 378-379)

A physical combination of two or more substances, such as salad dressing, trail mix, and chocolate milk.

2) How are mixtures classified? (pg. 378)They are either heterogeneous or homogenous.

- Heterogeneous mixture is when separate particles are big enough to see. For example, salad dressing, trail mix, and granola bars.

- Homogenous mixtures look the same throughout and have particles that are to small to see. For example, salt water, window cleaner, and cream cheese.

3) What are the parts of a solution? (pg. 380)

The solvent and the solute. The solvent is the part that does the dissolving (liquid) and the solute is the part that dissolves (solid).

* In a liquid-liquid, solid-solid, and gas-gas solution the part that is present in the greatest amount is the solvent and the part in the smaller amount is the solute.
