Mixtures & Their Separation Mixtures, elements and their compounds from a part of our everyday lives. Every time we breathe we are inhaling an element, oxygen gas. When we place salt on our food we are eating a compound, sodium chloride. When we drink a cold soft drink we are drinking a mixture. It may be useful to know how to separate some of these mixtures into their component parts. An example of this is the purification of drinking water.

Elements, Compounds & Mixtures Matter can be classified into two main groups: pure substances and mixtures.
![Elements Compounds Mixtures Pure substances are a type of mixture where the component Elements, Compounds & Mixtures Pure substances are a type of mixture where the component](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-5.jpg)
Elements, Compounds & Mixtures Pure substances are a type of mixture where the component parts cannot be separated by physical means and the composition is constant. Mixtures are a type of matter where the components can be separated by physical means.
![Elements Compounds Mixtures Pure substances can be further classified into elements and compounds Elements, Compounds & Mixtures Pure substances can be further classified into elements and compounds.](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-6.jpg)
Elements, Compounds & Mixtures Pure substances can be further classified into elements and compounds. Question: What is the difference between an element and a compound?

Elements, Compounds & Mixtures can be further classified into homogenenous and heterogeneous mixtures.

Elements An element is a pure substance that cannot be broken down into any simpler substance by ordinary chemical or physical means. We use the term ‘ordinary chemical means’ to exclude nuclear reactors.
![Elements The smallest particle in an element which has the same properties as the Elements The smallest particle in an element which has the same properties as the](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-9.jpg)
Elements The smallest particle in an element which has the same properties as the element is an atom. Elements are composed of only one kind of atom. Question: What are some examples of elements?
![Compounds A compound is a pure substance that contains two or more different types Compounds A compound is a pure substance that contains two or more different types](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-10.jpg)
Compounds A compound is a pure substance that contains two or more different types of elements which are chemically combined in such a way that their properties change.
![Compounds are composed of more than one kind of atom which will always be Compounds are composed of more than one kind of atom, which will always be](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-11.jpg)
Compounds are composed of more than one kind of atom, which will always be in the same proportion by mass. A compound can be represented by a formula which indicates the elements that the compound is made up of, and the ratio in which they have combined. Examples of compound are water (H 2 O), sodium chloride (Na. Cl) and methane (CH 4). The components of a compound cannot be separated by physical means.
![Mixtures Mixtures](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-12.jpg)
Mixtures
![Mixtures are a type of matter where components are not chemically combined and can Mixtures are a type of matter where components are not chemically combined and can](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-13.jpg)
Mixtures are a type of matter where components are not chemically combined and can be separated by physical means. Some of the physical methods of separating mixtures which will be investigated in our next lesson are filtration, evaporation, simple distillation, fractional distillation and paper chromatography. In a mixture the component parts are not in a fixed ratio and they retain their physical properties.
![Homogeneous Heterogeneous Mixtures can be either homogeneous or heterogeneous Homogeneous & Heterogeneous Mixtures can be either homogeneous or heterogeneous.](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-14.jpg)
Homogeneous & Heterogeneous Mixtures can be either homogeneous or heterogeneous.
![Homogeneous Mixtures Homogeneous mixtures are mixtures in which the properties and composition are uniform Homogeneous Mixtures Homogeneous mixtures are mixtures in which the properties and composition are uniform](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-15.jpg)
Homogeneous Mixtures Homogeneous mixtures are mixtures in which the properties and composition are uniform throughout the sample. We cannot distinguish the component parts from each other. Examples – air, salt dissolved in water and metal alloys like brass (a mixture of copper and zinc)
![Heterogeneous Mixtures Heterogeneous mixtures are mixtures in which the properties and composition are not Heterogeneous Mixtures Heterogeneous mixtures are mixtures in which the properties and composition are not](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-16.jpg)
Heterogeneous Mixtures Heterogeneous mixtures are mixtures in which the properties and composition are not uniform throughout the sample. We can distinguish the components parts from each other. Examples – mixtures of salt and pepper, sand water, and mayonnaise.

Solubility Questions: 1. What would happen if we kept adding teaspoons of salt to a glass of water? 2. Why does this happen?

Solubility The solubility of a solute is an indication of how much of the solute can dissolve in a fixed mass of solvent at a particular temperature. For example, we can find the solubility of sodium chloride in water by determining how much sodium chloride can dissolve in water at a particular temperature.

Solubility When no more solute can be dissolved in the solvent the solution reaches saturation point and we say that the solution is saturated.
![Solubility If any more solute is added to the solvent the solute will remain Solubility If any more solute is added to the solvent, the solute will remain](https://slidetodoc.com/presentation_image_h2/15ebb68a512b2c450bc49e24b015a876/image-39.jpg)
Solubility If any more solute is added to the solvent, the solute will remain in solid form and will be mixed in with the saturated solution.

Solubility Each solute and solvent combination has a specific solubility at a given temperature. The solubility of a solute in a solvent is determined by the structure of the solute and solvent, the temperature and the pressure.

Effect of Temperature on Solubility For most solid solutes in water, solubility increases as temperature increases.

Effect of Temperature on Solubility If a saturated solution is cooled, crystals of the solute will form since less of the solute can dissolve at the lower temperature.

Effect of Temperature on Solubility in water is usually expressed in grams of solute per 100 g of water. We can plot the solubility of a solute on a graph known as a solubility curve.
