Solutions as special mixes Flashcards
What are solutions?
Solutions are also mixtures
Some solutions can be made by mixing a ____ and ______ together
solid and liquid
What are the keypoints of soluble solutions?
*Soluble solids (solutes) can dissolve in a solvent
*The substances in solutions cannot be separated by sieving, filtering, hand sorting, settling and decanting
*Some solutes can be recovered by evaporating the solvent
What is the keypoint of saturated solutions?
A solution is saturated when no more solute can dissolve in a given amount of solvent
What is insoluble substances?
Some solids will not form a solution in water
Factors that affect the rate (time taken) of dissolving?
*Temperature of the mixture
*Stirring or shaking the mixture
*Grain size of the solute
What methods do you use to recover solutes?
*Filtering
*Settling
*Evaporating (crystallization)
