| Question | Answer |
|---|---|
| Heterogeneous | compostion is not uniform,size and shape of particles may vary. 2 or more clearly differnt components. |
| Homogeneouse | 2 or more differnt substances in a single phase,compostion is uniform ,not easily seperated. |
| Solution | Homogenouse mix of substances |
| Solvent | present in grater amounts, that which does the dissolving |
| Solute | prestent in the lesser amount, that which is being dissolved. |
| Suspension | When particles of a solute are too large to dissolve;instead they settle |
| Colloid | particles of solute are too large to dissolve but are too small to settle,appears to be one phase |
| Disersing Medium | solvent |
| Dispersed Phase | Solute |
| The Tyndall Effect | helps to tell the differnce between a collid and a true solution |
| Alloy | metals made by mixeing to other metals together |
| Electrolytes | dissolves in a solution as ions that will support an electric current. |
| Non electrolytes | dissolves but not as ions, wont support current. |
| Covalently bonded solutions | non electrolytes |
| Acids | Are covently bonded substances that shouldnt conduct electricy but they do because they are polar |
| Agiate | shake or stir to bring fresh solvent intocontact w/ undissolved solute |
| Crush or grind solute | surface area of solute that is in contact w/ the solvent which increases dissolving time |
| saturated solution | contains the maximum dissolved solute that it can depending on the t and vof the solvent. |
| Solutoin and equililbrum | Saturated Solution- no more solute is dissovling |
| Unsaturated Solution | solvant can dissolve more sollute for a given T and V |
| Super Saturated Solution | has benn forced to dissolve more solute than it should be able to for its T and V |
| Solubility | the amount required to form a saturated solution for a given T and V of solute. |
