22 terms
Terms | Definitions |
|---|---|
 Molarity | (M); moles of solute / L of solution |
| molality | (m); moles of solute / kg of solvent |
| mole fraction | (X); moles of solute / moles total |
| % composition | (m/m); grams of solute / grams total X 100 |
| (M) assume: | 1 L of solution |
| (m) assume: | 1 kg of solvent |
| % assume: | 100g solution |
| (x) molefraction assume: | 1 mol of solution |
| Hygroscopic | able to absorb water because of low vapor pressure |
| Dessicant | A type of hygroscopic material that is used as a drying agent |
| Deliquescent | A type of hygroscopic material that ends up ultimately dissolving itself |
| Brownian Motion | keeps colloid particles in motino because of the random vibrations |
| Effloresce | when water vapor pressure inside the crystal is greater than outside the crystal so that it loses its water of hydration |
| Anhydrous | meaning without water (has been effloresced) |
| Electrolyte | a substance that conducts electricity when dissolved or melted |
| Emulsion | a colloid thats dispersed phase and dispersal medium are liquids |
| Tyndall Effect | the scattering of light as it passes through a medium |
| Surfactant | allows water to separate and attack/absorb other agents easier because it interferes with the hydrogen bonding in water |
| Amorphous solid | a solid that lacks a regular molecular pattern |
| Kinetic theory | a theory about gases that gives the ideal gas equation |
| Sublimation | the change from solid to gas |
| Vapor pressure | pressure that is exerted by a vapor in equilibrium |
