Why is it good to separate mixtures?
To get their elements
What is the difference between solution and solubility?
A solution is a mixture of a solid, liquid or gas. All parts of the mixture are the same. You can’t see the separate substances
Name some separation techniques

Looking at the other investigation and use them aswell
What is a solute?
The liquid in which the solvent dissolves into
What is a soluble?
Something that can be dissolved
What does insoluble mean?
Something that can’t be dissolved
What does saturated mean?
The mixture can’t dissolve anymore
What does solubility mean?
How much solvent can be dissolved
How do you make solution?
You mix solute and solvent together
How do you get salt back?
By boiling the water
Why will more solute dissolve at a higher temperature?
Because the particles vibrate more so they dissolve more effectively
