Chemistry
| term | Definition |
|---|---|
| molal boling point depression constant | the change in boiling point for a !-molal solution of a nonvolatile molecular solution |
| concentrated solution | a solution containing a large amount of solute |
| solubility | the amount a substance that dissolves in a given quantity of solvent at a specific conditions of temperatures and pressures to produce a saturated solution. |
| surface tension | an inward force that tends to minimize the surface area of a liquid |
| molarity | the concentration of solute in a solution expressed as the number of moles of solute dissolved in ! liter of solution |
| unsaturated solution | a solution that contains less solute than a saturated solution at a given temp and pressure |
| surfacant | any substance that interferes with the hydrogen bonding between water molecules and thereby reduces surface tension |
| aqueous solution | water that contains dissolved substance |
| solvent | the dissolving medium in a solution |
| colligatuve property | a property of a solution that depends only upon the number of solute particle, and not upon their identities |
| miscible | describes liquid that dissolves in one another in all proportions |
| suspension | a mixture from which some of the particles settle out slowly upon standing |
| solute | dissolved particles in a solution |
| freezing-point depression | a difference in temp between the freezing point of a solution and the freezing point of the pure solvent |
| immiscible | describes liquids that are insoluable in one another |
| colloid | a mixture whose particles are intermediate in size between those of a suspension and a solute solution |
| electrolytes | a compound that conducts an electric current when it is in an aqueous solution in molten state |
| boiling-point elevation | the difference in temp between the boiling point of a solution and the boiling point of the pure solvent. |
| supersaturated solutions | a solution that contains more solute than it can theoretically hold at a given temp |
| Tyndall effect | scattering of light by particles in a colloid or suspension which causes a beam of light to become visible |
| nonelectrolye | a compound that does not conduct an electric current in aqueous solution on in molten state |
| molality | the concentration of solute in a solution expressed as the number of moles of solute dissolved in 1 kg of solution |
| Henry's Law | at given temp the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid |
| Brownian motion | the chaotic movement of collidal particles caused by collisions with particles of the solvent in which they are disspursed |
| strong electrlyes | a solution in which large portions of the solute exists as ions |
| mole fraction | the ratio of the moles of solute in solution the total number of both solvent and solute |
| concentration | a measurement of the amount of solute that is dissolved in a given quantity of solvent |
| emulsion | the colloidal dispersion of one liquid in another |
| weak electrolyes | a solution that conducts electricity poorly because only a fraction of the solute exists as ions |
| molal freezing point depression constant | the change in freezing point for a 1 molal solution of a nonvolatile molecular solution |
| dulite solution | a solution that contains a small amount of solute |
| saturated solution | a solution containing a maximum amount solute for a given amount of solvent at a constant temp and pressure |
| hydrate | a compound that has a specific number of water molecules bound to each formula unit |
