What is a solute?
The substance which is going to be dissolved
What is a solvent?
The liquid which is going to be doing the dissolving
What is a solution?
The resulting mixture of the solute dissolved in the solvent
What doe saturated mean?
A solution in which no more solute can be dissolved
What is suspension?

What does soluble mean?
A substance that can be dissolved
What does insoluble mean?

What is the solute, solvent and solution when dissolving salt into water?
Salt - solute
Water - solvent
Saltwater - solution
What unit is solubility measured in?
g per 100g of solvent
What is a solubility curve?
A graph that shows how solubility varies with temperature
What are the three parts of a solubility curve?
The line - saturated (shows that maximum mass of solid that can be dissolves at each temperature)
Below the line - soluble (less than the maximum solid, so it will all dissolve)
Above the line - insoluble (more than the maximum mass of the solid, so some will dissolve and some won’t. The mass that dissolves can be found by reading off the line)
