Q2W4CHEM

MIXTURES AND SOLUTIONS

QuestionAnswer
Concentrated solution A relatively large amount of solute compared with the amount of solvent. A concentrated solution is usually darker than a dilute solution because it has more solute in it.
Desalinization To remove salt from sea water.
Dilute Small amount of solute in a large amount of solvent.
Evaporation The process of allowing a liquid to evaporate and leave behind any solid that was in the liquid.
Filtration The process of separating a mixture of a liquid and a solid by straining it through a porous material.
Heterogeneous Not equally distributed.
Homogeneous Equally distributed. All solutions are homogenous mixtures because they have an even distribution of solvent and solute throughout.
Mixture Combining two or more different substances without those substances bonding together. Mixtures can be heterogeneous (pulpy orange juice) or homogeneous (soda pop).
Polar Different parts of a molecule display slightly different charges. Water is a polar molecule because the hydrogen atoms are slightly positive and the oxygen is slightly negative.
Saturated The maximum amount of solute has been dissolved in the solvent. A saturated solution cannot hold any more solute.
Sieving A method of separating solids of various sizes. Sieving only works with solid substances.
Solubility The maximum amount of solute that a solvent will dissolve at a given temperature. Solubility is affected by temperature, agitation, and the size of the solute.
Solute The substance in the smaller amount in a solution. Sugar is the solute in a solution of sugar water.
Solution A type of mixture made when a solute is dissolved in a solvent. Bronze is a type of solution made of copper and tin. All solutions are homogeneous.
Distillation The evaporation and subsequent collection of a liquid by condensation as a means of purification. 1.The evaporation and subsequent collection of a liquid by condensation as a means of purification: the distillation of water.
