What is a solution ?
A solution a is a homogeneous mixture
What is a aqueous solution?
A aqueous solution is when water is the solvent
What is a solute ?
A solute is the substance being dissolved
What is a solvent ?
A solvent is a substance that dissolves the solute.
What is the solubility of a substance?
The solubility of a substance is the maximum amount of solute that can be dissolved in a certain amount of solvent.
What can affect the solubility of a substance ?
Three things that can affect the solubility of a substance is pressure, temperature, and the type of solvent/solute
What is the concentration of a solution ?
The concentration of a solution is the amount of solute in a solution

What is the equation to find the Concentration as %
It’s g/100mL
grams over 100ml
What does PPM stand for ?
It stands for Parts Per Million
When is PPM used ?
PPM is used when the solute is very small
