Properties of mixtures
There are no chemical changes in mixtures. The properties do not change when a mixture is formed. Each substance has the same chemical makeup it had before the mixture is formed. This means it keeps its identity. For example, in pizza you can take apart the pizza and its toppings. The same goes for a salad. You can take it apart.

solutionsA solution is caused by dissolving. This is a process of a substance separating and spreading equally throughout a mix. The solute of a substance is the substance that is dissolved. The solvent is the substance in which the solute is dissolved. The solute must be soluble in order to mix with the solvent. The word soluble means able to be dissolved. When two liquids or gases are dissolved, the substance that has the greater quantity is the solvent.
a measure of the amount of solute dissolved in a given amount of solvent is the concentration. the concentration is expressed as grams of solute per millimeter of solvent. A dilute solution would be a little bit of solute per solvent. A concentrated solution is alot of solute per solvent. |
