Will the vapor of a mixture have a higher percentage of the more volatile component? | yes |
distillation | heating a liquid to produce a vapor that is enriched in the more volatile, and then condensing this vapor to produce a liquid that will be enriched in the volatile component |
when do we have a heterogeneous mixture? | when the solutes sink to the bottom of the solvent. |
particles with physical dimensions of at least what in order to scatter visible light and therefore appear cloudy? | dimensions of at least 400 nm and 750 nm |
colloids | somewhere between a homogenous solution and a heterogenous mixture |
hydrophilic means what? | water loving |
Hydrophilic colloids have solutes with what? | structures on their surface that are able to hydrogen bond with water |
hydrophobic means what? | water fearing |
