=Class notes= =Pure and Impure= A pure substance is made of one type of particle An example of a pure substance is water

An impure substance is made of many types of particles An example of an impure substance is dirt Mixtures can be made of impure and pure substances mixed together.

=Separating= //__( means to Divide into groups based on their properties)__//

We can separate a mixture back into its component parts if we know some of the components properties. For example we can separate iron pins from sand easily because we know iron is magnetic and sand is not. So we can use a magnet to attract the pins away form the sand.

Some other properties we can use are: When something dissolves in a liquid we say it is soluble. The liquid it dissolves in is called the solvent and the stuff that dissolves is called the solute. If a solute does not dissolve in the solvent it is said to be insoluble.
 * if a salt is dissolved in water we can evaporate the water leaving the salt
 * if dirt is in water we can filter out the dirt and leave the water
 * if oil is mixed with water we can let the oil settle on the surface and decant (tip) the oil off.
 * ** __ Testing for Solubility __ **
 * When something dissolves in a liquid we say it is soluble. The liquid it dissolves in is called the solvent and the stuff that dissolves is called the solute.

Solute + Solvent > solution
Temperature - the experiment where we heated the water in a test tube and added copper sulfate showed us that we could keep adding copper sulfate while the temperature of the water was high.
 * What affects solubility **

Surface area – If we increase the surface area of the solute by crushing it it will dissolve faster.

Concentration. If we have lots of a solute in a solution its called concentrated. If there is not much its dilute.

Suspensions When a substance does not dissolves but floats in the solvent its called a suspension. Eventually it will settle to the bottom of the flask. Then its called a sediment.

Colloids Are tiny insoluble particles that never settle as sediment. Examples are paint,

Aim: to make a filtering cone out of filter paper and separate a mixture. // Method // Half fill your 100 mL beaker with water. Add your insoluble substance to the water and stir with the stirring rod.up the equipment for filtering as shown in the top diagram in Sift and separate. Fold filter paper into a fluted filter cone Place the filter paper in the funnel and moisten with clean water to hold the filter paper in place. Pour your mixture into the filter paper.
 * Filtration in the laboratory **

What did you observe? yellow before we added it to water, When we added it to water it looked a bit green, After we filtered it the yellow residue stuck to the filter paper while the blue filtrate was collected in the conical flask. > || Does not dissolve in water || Does not dissolve in water || > || Sinks in water || Sink in water || > || Not magnetic || magnetic ||

 * **Discussion**
 * Describe the appearance of your mixture in the beaker before filtration. Did it form a suspension or sediment, or float on top? __//Formed a suspension and a sediment.//__
 * The liquid passing through the filter into the conical flask is called the filtrate . Describe your filtrate. __//The FIltrate was// //Green or blue in colour but we can see through it.//__
 * Examine your filter paper. The material trapped by the filter paper is called the residue . Describe your residue. __//The residue was y////ellow//__
 * Filter paper is like a sieve with small holes in it. Explain how the filter paper worked like a sieve in this experiment. __//The holes in the filter paper were smaller than the lumps of chalk that got stuck on the filter paper but big enough to let the water and copper sulfate pass through.//__
 * ** //__ Separating techniques __// **
 * You can separate solids from mixtures by using a range of techniques. To do the separating you need to know the properties of the substances in the mixture. Choose a property that is different to any others in the mixture and then choose a technique that will allow you to separate the solids
 * Example 1
 * ** __ Separating sand and iron filings __ **
 * The properties of these are
 * || Properties of sand || Properties of iron filings ||
 * Examine your filter paper. The material trapped by the filter paper is called the residue . Describe your residue. __//The residue was y////ellow//__
 * Filter paper is like a sieve with small holes in it. Explain how the filter paper worked like a sieve in this experiment. __//The holes in the filter paper were smaller than the lumps of chalk that got stuck on the filter paper but big enough to let the water and copper sulfate pass through.//__

__ Separating using density __ Density is a property of a substance which describes how tight the particles (atoms) in a substance are packed. Particles in foam are not tightly packed while particles in steel are tightly packed. It is also true that objects of the __same size__ can have different weights (or mass) the heavier object will have the greatest density. The following techniques separate components of a mixture because each component has a different density.

Substances with a greater density will separate out of solution that is spun at high speed before the lighter particles will settle. This method is used to separate red blood cells out of blood plasma. Try this: muddy water in a bucket and spin it around- what happens? Draw a picture.
 * //__ Using a centrifuge to separate substances __// **

__Using a separating funnel__ this is used to separate liquids of different densities. The tap at the bottom of the funnel can be opened to allow the most dense liquid to drain out. Draw a picture of this device.


 * //__ Separating solutions In a mixture __// **

Paste in your results.
 * // Chromatography // ** . This can be used to separate the colour inks in a pen. It works because the different colours have a different weight. The lightest ones travel the furthest up the filter paper.

Distillation
This will separate different solutions if they have a different boiling point. Eg separating alcohol, from water. Copy the picture below

The distillation apparatus works because water boils at 100 degrees C. The liquid water is heated so it changes state from a liquid to a gas. The water gas is passed along a cooling tube – called the condenser. The condenser is a __//**glass tube inside a glass tube**//__. This forms a sleeve. Cold water is passed around the sleeve. In the condenser the water changes state back to a liquid. This liquid is now collected in a container. On your diagram mark the direction the water flows.

Collecting water in the desert. We made a bush still by collecting leaves and putting it inside a closed container. We hope the water will evaporate out of the leaves and become a gas. The gas should cool down on the underside of the plastic and water should run into our collecting jar. Draw a picture of our bush still

Absorption
Absorption is a separating technique that relies on one of the substances being able to be absorbed into something like a sponge or kitchen paper. When you buy meat the packaging some times has a small sponge like pad that sits below the meat to separate the meat from meat juice and blood. It does this by soaking up the blood. Describe example of absorption;

Froth flotation
> Some times chemicals or ores will stick to bubbles of detergent or froth. because this floats we can use collect the froth along with the chemical using a scoop. They use this technique in mining copper where they separate the copper ore from the surrounding rock after all the rock is crushed. > > Floculants or floculation. > This is a method to make a suspension clump together so its easy to pick up the bigger bits. You may use this to clean up the water in your pool. If the water is cloudy or murky or muddy you can use a flocculant whihc will make the bits clump. They then fall to the bottom of the pool and you can vacuum them up. > > > > > =Distillation=
