Water Unit E

Do Now: Quietly read page 63 Answer questions 1-4

Mixtures Mixture – lots of different things combined together – Usually sorted using filtration

When Filtering Doesn’t Work Dissolved – a compound that decomposes into water Soluble – a substance that dissolves Insoluble – a substance that does not dissovle

Solution Solution – a solid dissolved into a liquid Solvent – liquid in a solution Solute – the solid in a solution

Types of Solutions Transparent – See through – All solutions are transparent Opaque – Cloudy – A mixture, not a solution – Maybe over-saturated: some solute dissolved, but to much solute was added to the solvent

Do Now: Collect your book from the front Correct your water cycle diagram What needs to be added to the diagram below?

Solubility What is a solvent? What is a solute? What does this produce?

Particles in a Solution Particles in a solution will combine. – Saturated – no more solvent will dissolve

Supersaturated Supersaturated – forcing more solvent to dissolve into the solute – Unstable solution

Define each of the following: Unsaturated – Saturated – Over-saturated – Supersaturated -

ble-salts ble-salts

Lab Tomorrow: You will be creating a supersaturated solution – Describe the steps needed to do this. Observations you should be making. – List observations.
