Ch. 11Lesson 4What are
mixtures and solutions?

Problem: What is the easiest way to separate a mixture?
Information: mixtures can be separated by their
different densities-mixtures do not form compounds
Hypothesis:
Activity- Separating a Mixture

mixturedifferent materials are together but do not bond to form compounds

mixturematerials can be separated b/c have different properties

alloymetal that is mixture of elements
ex. brass, bronze

solutionspecial mixture-substances are spread out evenly & do not settle

parts of a solution
solute= smaller amount solvent= larger amount

In a salt water
solutionsolute= salt
solvent= water

saturated solution
contains all the solute that can be dissolved w/out changing temp.

concentrated solution
has so much solute-almost saturated

dilute solution
far from being saturatedsmall amt. of solute
