| 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.
🗑
