Mechanical Mixtures Has more than one type of particle You can see the different substances in mechanical mixtures. Ex. Concrete Other examples?
Solutions When two or more substances combine to form a mixture that is uniform (looks the same throughout) Appears to contain only one kind of particle. Examples: Shampoo and syrup. Other examples?
Parts of Solutions Solute- is the substance that dissolves Solvent- is the substance in which the solute dissolves. Solute and solvent combine to form a solution. There is usually less solute than solvent in a solution. Iced tea- Crystals (solute or solvent?) - Water (solute or solvent?)
Concentration Describes the amount of solute in a solution (what is solute again??) seen on the label of many products Shown in many ways: g/L most common which means mass of solute in 1L of the solution
Solubility Describes how easily a solute will dissolve in a solvent to make a solution Soluble: when a substance will dissolve in a solvent. Insoluble: when a substance will NOT dissolve in a solvent
Miscible vs. Immiscible Miscible: is capable of being mixed. Ex. Milk and water. Immiscible: incapable of being mixed. Ex. Fuel (gasoline) and water are immiscible Ex. Water and oil
Mixtures and Solutions Matter is made up of pure substances and mixtures Pure substances are made up of elements and compounds Mixtures are made up of mechanical mixtures and solutions.

Review: To remember solute vs. solvent Solute- the substance that dissolves Usually less of Solvent- the substance that does the dissolves Usually more of Another Hint: “u” in solute comes before “v” in solvent so your going to put solute in the solvent. Solvent dissolves the solute.
Other Trick… use if you want Remembering Solute vs. Solvent: Solute (6 letters long) Solvent (7 letters long) The solute is shorter/smaller/less of, if there is less of it, it will dissolve
Purifying Water Water treatment plants One method; add alum to impure water, bacteria and dirt stick to alum and sink. Therefore easily separated. Another step uses a charcoal filter to remove dissolved impurities Lastly adding chlorine, kills any of the bacteria that are still present.
Distillation Distillation is a way to get clean water. Process in which water is boiled and the steam is collected and it condenses to form pure water. Solar water distillerSolar water distiller
Separating Mixtures 4 Main ways to separate mixtures: Straining (separation by size) ie. Using filter paper Using a magnet (separates iron parts) Evaporation (sugar and water) Dissolving (sugar and sand)
