### Unit 10 solutions 1

1. 1. Unit 10<br />SOLUTION CHEMISTRY!<br />
2. 2. What is a solution?<br />A solution is an answer to a problem.<br />OR<br />A solution is a homogenous mixture of 2 or more substances.<br />
3. 3. Solutions have two parts to them…<br />Solute: the substance that is being dissolved.<br />Ex: SALT (NaCl), Chocolate!<br />Solvent: the substance that is doing the dissolving<br />Ex:WATER , Milk<br />
4. 4. WATER<br />Water is known as the Universal Solvent<br />It is known as this because of polarity<br />The hydrogens have a partially positive charge<br />The oxygen has a partially negative charge<br />
5. 5. More Water<br />When water acts as the solvent the process is called hydration.<br />When you are deHYDRATED that means you haven’t had enough WATER<br />
6. 6. Solvation <br />If another substance acts as the solvent the process is called solvation, which means the solvent surrounds the solute and pulls it apart making it dissolve.<br />
7. 7. Concentration and Solubility<br />A solution can be measured by its concentration. There are three basic measurements of solubility.<br />
8. 8. Saturated Solutions<br />Saturated means the solution contains the maximum amount of solute that can be dissolved in a solution.<br />
9. 9. Supersaturated Solutions<br />Supersaturated means the solution contains more than the maximum amount of solute that can be dissolved in the solution.<br />
10. 10. Unsaturated Solutions<br />An unsaturated solution means it contains very little solute.<br />
11. 11. Saturated<br />UN Saturated<br />SUPER saturated<br />
12. 12. To dissolve or not to dissolve….<br />Not all solutes are able to dissolve in solvents<br />If a solute DOES NOT dissolve is a solvent it is called immiscible<br />If a solute DOES dissolve in a solvent it is called miscible<br />http://www.youtube.com/watch?v=ek6CVVJk4OQ<br />
