Pure Substances
If you stir a spoonful of sugar into a large glass of water and it dissolves completely, you have created this type of solution that can still hold more solute.
Unsaturated solution
What is the difference between heterogeneous and homogeneous mixture?
Homogeneous looks the same throughout and you can't take the mixture apart. Heterogeneous can be taken apart and is very easy to tell the parts of the mixture.
This unstable type of solution is made by heating a liquid to dissolve extra solute, then cooling it down carefully so it holds more than it normally should.
What is a supersaturated solution?
What does homogeneous mean?
When a mixture mixes evenly and looks the same throughout.
This happens to the speed of particles when you add heat energy to a substance.
What is they speed up / move faster?
This separation method involves leaving a muddy mixture alone so that gravity can pull the heavy, dense solid particles down to the bottom of the container.
Settling
This state of matter has a fixed volume but no fixed shape, allowing its particles to slide past one another and take the shape of their container.
This method lets you recover solid salt from salt water by heating the mixture until the liquid turns into vapor, leaving the dry salt behind.
Evaporation
This is what you will find in the spaces between particles in a pure substance.
What is empty space?
Give an example of a homogeneous mixture that is not a liquid.
A nail used for wood work.
To separate a mixture of salt, water, and sand, you should use this mechanical method to catch the sand first, before evaporating the water to get the salt.
What is filtration?
