What is a homogenous mixture?
A homogenous mixture is 2 substances that can’t be seen by the naked eye
What is a heterogenous mixture?
2 substances that can be seen by the naked eye
What is soluble
What is residue
What is insoluble
Soluble= It dissolves Residue= what’s left behind Insoluble= does not dissolve
If the solute dissolves what is the mixture called?
A solution
What’s a suspension
a) solute and solute, it’s homogenous
b) solute and solvent, it’s homogenous
c) solute and solvent, it’s heterogenous
d) solvent and solvent, its heterogenous

What’s the difference between a pure substance and a mixture
Pure substances have 1 type of particles

What is a solute?
The substance being dissolved in a solvent
What is a solvent?
The substance that the solute is being dissolved in
What is the universal solvent and why?
Water since most solvents dissolve in it
What is a solution?
- homogeneous mixture
- solute dissolves in solvent
What is a suspension?
- heterogenous mixture
- solute doesn’t dissolve in solvent
- large particles sink to the bottom
What is an emulsion?
- heterogenous mixture
- two solves that don’t combine
What is a colloid? What is the Tyndall effect?
- homogenous mixture
- solute and solvent half combine
- Tyndall effect: particles are seen when the substance is held under a light
