| Question | Answer |
|---|---|
| What is the name of two phase mixtures that consist of a solid in a liquid? (They are somewhat rigid) | gels |
| What is the name of two phase mixtures that consist of a solid in a liquid, but the mixture is more like a liquid or a viscous liquid? (Think thick liquids) | sols |
| What is the name of mixtures that contain two or more distinct liquid phases? (These phases cannot be blended into eachother) | Emulsions |
| What words means cannot be blended into eachother? | immiscible |
| When a gas is whipped into a liquid so that it makes a mixture of tiny bubbles with the liquid, you get what? | foam |
| Tiny solid particles or liquid drops that are dispersed in a gas form an? | aerosol |
| Metal mixtures are called _____ and are metal solutions. | alloys |
| ________ _______ is what happens when particles between 1nm and 1um are even mixed and do not settle out. | collodial dispersion |
| ______ are fluid mixtures whose dispersed particles, whether solid or liquid, are larger than about 1um in size. The particles settle out over time. | Suspensions |
| What is the name of the unbroken phase of a mixture in which the other phases are mixed? | continuous phase |
| What is the name of the broken phase in a mixture | dispersed phase |
| An example of an emulsion is? | mayonnaise |
| An example of foam is? | shaving cream |
| An example of a colloid is? | fog |
| An example of suspension is? | blood |
| This is the name for a way to tell colloids and solutions apart using a beam of light... | Tyndall effect |
| Can mixtures or pure substances be seperated by using their physical properties? | mixtures |
| These are homogeneous mixtures of pure substances in a single phase... | solutions |
| In a solution, the substance that does not dissolve or of which you have the most is called..? | solvent |
| In a solution the substance that is dissolved or of which you have the least is called the...? | solute |
| Solutes can or cannot be filtered out of a solution? | cannot |
| True solutions are ___ and do NOT scatter light as in the Tyndall effect. | transparent |
| Components of a solution are or are not chemically combined? | Not |
| This is called the universal solvent. | Water |
| Tiny solid particles or liquid drops that are dispersed in a gas form? | aerosol |
| Solutions are ______ mixtures. | homogenous |
| Solutes CANNOT be _______ out of a solution. | filtered |
| Solutes Do or do Not settle out of a solution? | DO NOT |
| Solid solutions are often a mixture of metals called? | alloys |
| When solute ions are pulled apart by the solvent it is called? | dissociation |
| The surrounding of a solute particle by solvent molecules is called? | solvation |
| The surrounding of a solute particle by water is called? | hydration |
| A substance is _______ when it CAN be dissolved by a solvent. | soluble |
| Like dissolves _______ | like |
| Liquids that can freely mix in any proportion are said to be ______. | Miscible |
| _________ is the maximum amount of solute at a given temperature. | solubility |
| Solubility is usually expressed in ______. | grams/100 ml of solvent |
| Solutes that cannot mix in certain solvents are said to be? | insoluble |
| Insoluble liquids are _______. | immiscible |
| Immiscible means not _______. | mixable |
| An example of immiscible liquids is ______ ______. | Italian dressing |
| Factors that affect solubility are temperature and..? | pressure of gases |
| When a solution holds all the solute it can normally is said to be? | saturated |
| When a solution holds MORE that it should at a certain temperature, it is said to be..? | supersaturated |
| When a solution can still hold more solute is? | unsaturated |
| These increase the rate of solution. | temperature, stirring, and surface area. |
| This is the amount of solute in a certain amount of solvent or solution... | Concentration |
| This is the mass in grams of solute per 100g of solution | percentage by mass |
| Grams of solute + grams of solvent= | grams of solution |
| Avagadro's number | 6.022 * 10^23 |
