solutions
| Term | Definition |
|---|---|
| Soluble | we mean capable of being dissolved |
| solutions | is a homogeneous mixture of two or more substances uniformly dispersed through out a single phase |
| solvent | the dissolving medium in a solution |
| solute | the substance dissolved in the solution |
| suspension | particles in solvent are so large that they settle out unless the mixture is constantly stirred |
| colloids | particles that are intermediate in size between those in solution and suspensions form |
| electrolyte | a substance that dissolves in water to give a solution that conducts electric current |
| nonelectrolyte | a substance that dissolve in water to give a solution that does not conduct electric current |
| solution equilibrium | the physical state in which the opposing processes of dissolution and crystallization |
| unsaturated solutions | contains less solute than a saturated solution under the existing condition |
| supersaturated solution | solution that contains more dissolve solute than a saturated solution contains under the same conditions |
| solubility | of a substance is amount of that substance required to form a saturated solution with specific amount of solvent a specified temperature |
| hydration | the solutions process with water as a solvent |
| immiscible | liquids that are not soluble in each other |
| miscible | liquids that dissolve freely in one another in any proportion |
| Henry's law | the solubility of a gas in a liquid is directly proportional to the partial pressure of gas on the surface of liquids |
| effervescence | the rapid escape of a gas from liquid in which it is dissolved |
| solvated | a solute particle that is surrounded by solvent |
| enthalpy | the net amount of solute dissolves in a solvent |
| concentration | solution is measure of the amount of solute in a given amount of solvent |
| molarity | number of moles of solute in one liter solution |
| Molality | concentration of solution expressed in moles |
