Mixtures
What is a Mixture
What is a Homogeneous mixture
What is solubility
measure of how easy a substance dissolves.
Why do scientists want to be able to separate mixtures
Can mixtures be made of the substances in the same phase
What is Mixtures can be in the same phase
Mixture that is not uniform, or not the same throughout
What is a heterogeneous mixture
How do we measure solubility
by how well a substance dissolves in water
What do most separation techniques do
Separate components of a mixture by manipulating the physical properties of a substance in the mixture.
Can solids mix with liquids
Yes solids and other substances can mix even in different phases.
Most common homogeneous mixture
What is a solution
What is the measurement of solubility and what does it tell you
Grams per, and its measurement tells you how much of a substance dissolves in 100 grams of water
What is Mechanical separation
Physical separation of a mixture using your hands or tools
Give two examples of mixtures in the same phase
Air, and soil. soil, and gasoline. gasoline, and air
What happens in a solution
one substance dissolves into another substance
How much mass takes up a space
What is Magnetism
Give two or more examples of mixtures made of substances in different phases
Soda, and salt water. salt water and blood, blood and soda
how many phases are in a solution
A single phase
