| Questions | Answers |
|---|---|
| Henreys law | the solubility of a gas in a liquid is proportional to the partial preassure of a gas |
| solute | the component of a solution that is present in the lesser quantity |
| solvent | the component of a solution that is present in the greater quantity |
| solution | the general term for a solute dissolved in a solvent |
| dipole | a region in a polar molecule with a partial negative and a partial positive charge |
| net dipole | the overall direction of partial negative charge in a molecule |
| polar solvent | a dissolving liquid composed of polar molecules |
| nonpolar solvent | a dissolving liquid composed of non polar molecules |
| like dissolves like rule | the principle that solubility is greatest when the polarity of the solute is similar to that of the solvent |
| miscible | refers to liquids that disolve completly in one another |
| immiscible | refers to liquids that do not dissolve in one another and seperate into two layers |
| solvent cage | a cluster of solvent molecules surrounding a solute particle in solution. |
| colloid | a mixture in which the dispersed particles range from 1 to 100 nm |
