Class Presentation Mixtures & Solutions Shannon Science 8 MATTER is anything that has mass and takes FACT upMATTER space Water can be can found be can be naturally on earth as a and a gas. canliquid, be condenses freezes tosolid, to solid liquid melts to gas evaporates to MIXTURES are can be Two or more kinds of matter put together separated by can be solutions made when one kind of material dissolves in another which cannot be separated by filtration sorting filtration using sieves using magnets floating vs. sinking evaporation distillation chromatography MIXTURES can have can have no visible parts visible parts are called like SOLUTIONS sand and water like oil and vinegar iron and sand salt and water Kool-Aid® How would you separate a mixture of sand and water? How would you separate a mixture of sand and water? ANSWER: Pour the mixture through a filter. The water will go through the filter leaving the sand behind. How would you separate a mixture of iron and sand? How would you separate ANSWER: a mixture of iron and sand? Use a magnet to separate the iron from the sand. How would you separate a mixture of salt and water? HINT: Salt and water form a solution. How would you separate a mixture of salt and water? ANSWER: Heat the water until the water evaporates. The salt will remain. HINT: Salt and water form a solution. INVESTIGATING SOLUTIONS 1. What is a saturated solution? A solution in which no more solid material will _________________________________________ dissolve; additional material settles to the _________________________________________ bottom. _________________________________________ 2. How can you tell when a solution is saturated? No more material will dissolve in the solution. _________________________________________ _________________________________________ _________________________________________ INVESTIGATING SOLUTIONS 3. What is solubility? Solubility is the property that substances _______________________________________ have of dissolving in solvents, such as the _______________________________________ solubility of salt in water. _______________________________________ 4. What is meant by the solubility of a material in water? How much of the material dissolves in the _______________________________________ water. _______________________________________ _______________________________________ INVESTIGATING SOLUTIONS 5. What is a concentrated solution? A solution containing a large amount of _______________________________________ material dissolved in a measured amount of _______________________________________ liquid. _______________________________________ 6. What is a dilute solution? A solution containing a small amount of _______________________________________ material dissolved in a large amount of liquid. _______________________________________ _______________________________________ Which is a saturated solution? A B How do you know? Which is a saturated solution? A B No more material will dissolve in solution A. Which is a concentrated Kool-Aid® solution? A B How do you know? Which is a concentrated Kool-Aid® solution? A B Solution A is darker in color than Solution B. Which is a dilute saltwater solution? B A Note: A and B have the same volume. How do you know? 100 g 125 g Which is a dilute saltwater solution? A 100 g B Solution A has less mass 125 g than Solution B.
