| Are Saturated curves on, above, or below the curve? | On |
| Are Supersaturated curves on, above, or below the curve? | Above |
| Are Unsaturated curves on, above, or below the curve? | Below |
| What 4 things might affect how well/quickly solute dissolves? | -Temperature -Motion -Surface Area -Type of solvent |
| _________ are homogeneous mixtures that are well mixed, evenly distributed and their small parts are dissolved. (Ex. Kool-Aid, Soda,Air,etc.) | Solutions |
| A ______ ______ consists of larger particles that are DIFFERENT from each other and are not well mixed. Components are not evenly distributed. You CAN see the parts. (Ex. Pepperoni, pizza, sand & water, salad dressing, muddy water, oil & water,etc.) | Heterogenous Mixture |
| A _____ is where 2 or more substances come together but do NOT combine to make a new substance. (No Chemical bond, it is a physical change) (Ex. Air, Salt, Water, Blood, Soda, etc.) | Mixture |
| A ______ is another example of a homogeneous mixture that is well-mixed and has evenly small parts that do NOT dissolve. You cannot see through it. (Ex. Shaving Cream, Toothpaste, Milk, Fog, Paint, Etc. ) | Colloid |
| When a substance is _____, it cannot dissolve into a specific solvent. (Ex. Sand & Water, Oil & Water, Sugar & Oil, Etc.) | Insoluble |
| ______ is how much solute dissolves in a given amount of Solvent. (HOW MUCH- Not how fast) | Solubility |
| _____ are heterogenous mixtures that are not well-mixed and some of the particles eventually settle out. They usually have "Shake Well" label on them. (Ex. Chocolate Milk, Liquid Medications, Salad Dressings, Etc.) | Suspensions |
| The _____ of a solution tells you how much solute is present compared to the amount of solvent. | Concentration |
| When a concentrated solution has more solute than the amount of solvent it is concentrated to be ____. | Dilute |
| The ____ is the part in a solution that does the dissolving. (Ex. Water is a Universal ____.) | Solvent (For Both) |
| ____ solutions contain all of the solute that it can hold under the given conditions. | Saturated |
| _____ means large amount of solute that dissolves in solvent. (Ex. Sugar & Water) | Soluble |
| A ____ is a small amount of a substance that is being dissolved. It seems to disappear. (Ex. Sugar, Kool-Aid, Salt, Powder, Etc.) | Solute |
| A _____ _____ is when 2 or more substances are evenly mixed and evenly distributed. You can't see the individual parts. (Ex. Shaving Cream, Kool-Aid, Milk, Toothpaste, Shampoo, Etc.) | Homogenous Mixture |
| In a ____ ___ solution, a saturated solution is cooled slowly and sometimes the excess solute remains dissolved for a period of time. It contains MORE than the normal amount of solute. | Super Saturated |
| Solutions are ____ if they have LESS solute than they would need to become saturated. | Unsaturated |
| We have a larger amount of SOLUTE or SOLVENT. | Solvent |
| Why does stirring/shaking help dissolve the solute faster? | Stirring moves molecules so there is more opportunities for water & sugar to meet. |
| Why does temperature help to dissolve the solute faster? | Increased temperatures make the molecules faste and can allow them to sollide and attract easier |
| Why does the surface area of particles help dissolve the solute faster? | Increasing the surface area causes more sides of the solute to be exposed for the solvent to contact/attract to. |
| What does Polar Vs. Non-Polar have to do with dissolving the solute faster? | Polar Molecules attract best to other polar molecules. -Oil is non-polar. Oil and Water (Polar) don't attract -Sugar is Polar. Water (Polar) and sugar attract. |
| What is surface area? | Surface area is how many sides there is for molecules to attract to. |
