cava s2d24 chem 303 2.08 Separating Solutions
| Question | Answer |
|---|---|
| Distillation uses [...] differences to separate *one* liquid from the rest of a mixture. | Distillation uses boiling point differences to separate *one* liquid from the rest of a mixture. |
| [...] is the process by which a mixture is separated by being allowed to flow along some stationary substance. | Chromatography is the process by which a mixture is separated by being allowed to flow along some stationary substance. |
| If liquids are separated by running them up a slip of paper, then paper is the [...] phase because it doesn't move. | If liquids are separated by running them up a slip of paper, then paper is the stationary phase because it doesn't move. |
| In gas chromatography, a gas is mixed with a carrier gas such as helium (the [...] phase) and allowed to travel through a column of liquid or solid. | In gas chromatography, a gas is mixed with a carrier gas such as helium (the mobile phase) and allowed to travel through a column of liquid or solid. |
| [...] is a kind of distillation that separates multiple parts (or 'fractions') of a mixture. | Fractionation is a kind of distillation that separates multiple parts (or 'fractions') of a mixture. |
| Distillation separates [...] part(s); fractionation separates [...] part(s) of a mixture. | Distillation separates one part; fractionation separates multiple parts of a mixture. |
| Crude oil (petroleum) is refined using [...] to separate out gasoline, mineral oils, kerosine, natural gas, etc. | Crude oil (petroleum) is refined using fractionation to separate out gasoline, mineral oils, kerosine, natural gas, etc. |
| Filtering is used to separate the [...] part of a solution from the liquid portion (think coffee). | Filtering is used to separate the solid part of a solution from the liquid portion (think coffee). |
| Osmosis is a kind of [-ing]. Hint: it can separate parts of a solution. | Osmosis is a kind of filtering. |
| Osmosis is when water passes through a membrane (thin filter) that lets water through, but [...]. | Osmosis is when water passes through a membrane (thin filter) that lets water through, but not much else through. |
| A [m-] is a thin layer... of pretty much anything. | A membrane is a thin layer... of pretty much anything. |
| Distillation uses boiling point differences to separate *[...]* liquid from the rest of a mixture. | Distillation uses boiling point differences to separate *one* liquid from the rest of a mixture. |
| Chromatography is the process by which a mixture is separated by being allowed to flow along some [...] substance. | Chromatography is the process by which a mixture is separated by being allowed to flow along some stationary substance. |
| Fractionation is a kind of distillation that separates multiple [...] (or 'fractions') of a mixture. | Fractionation is a kind of distillation that separates multiple parts (or 'fractions') of a mixture. |
| Fractionation is a kind of distillation that separates [...] parts (or 'fractions') of a mixture. | Fractionation is a kind of distillation that separates multiple parts (or 'fractions') of a mixture. |
