Term
|
Definition
| A homogeneous mixture; consists of solutes dissolved in a solvent. |
|
|
Term
| What is the difference between a solute and a solvent? |
|
Definition
| A solute is what is dissolved in a solution. For example, chocolate syrup. A solvent is what the solute dissolves in. For example, Milk. Creating a solution of: Chocolate Milk. |
|
|
Term
| What is the difference between saturated, unsaturated, and supersaturated? |
|
Definition
| Saturated- Contains the maximum amount of solvent a for a solution. Unsaturated-Contans the lowest amount of solute possible. Supersaturated- A solution contains more solute than possible. |
|
|
Term
| What is the difference between dilute and concentrated? |
|
Definition
| Dilute- It contains a smaller amount of solute in relation to the solvent. Concentration- Contains a larger amount of solute in relation to the solvent. |
|
|
Term
| What 3 factors affect the rate in which a substance dissolves? How do these factors affect the rate of dissolution? |
|
Definition
| Temperature-Warmer means faster. Agitation- Stirring increases dissolving. Surface Area- Smaller area is easier to heat or stir. |
|
|
Term
| What factors affect the rate of solubility? How do these factors affect the rate of solubility? |
|
Definition
| Temperature and Pressure. |
|
|
Term
| How can the solubility of a solution be written? |
|
Definition
| Grams of solute OVER 1 liter of solvent. Grams of solute OVER one hundred grams of solvent. |
|
|
Term
What is a polar molecule?
A nonpolar molecule? |
|
Definition
Polar- has a positive side and a negative side.
Nonpolar-Electrons are shared 2 atoms. |
|
|
Term
|
Definition
| A dispersion of a liquid in a liquid. |
|
|
Term
| How does an emulsifier work? |
|
Definition
| Grease and Oil aren't soluble with water, so soap connects them. |
|
|
Term
| Give two examples of emulsifiers. |

|
|
Term
| What is a suspension? What is a colloid? Give an example of each. |
|
Definition
Suspension- a mixture from which some of the particles settle out upon standing. Like a snowglobe.
Colloid- Mixture where particles are intermediate in size between those of a suspension an a solute. Like gel. |
|
|
Term
| How do solutions differ from suspensions and colloids? |
|
Definition
| Solutions are homogeneous. |
|
|
Term
| What is the Tyndall effect? What substances exhibit the Tyndall effect? |
|
Definition
| The scattering of light throughout a substance. Colloid and Suspension. |
