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. |
