Solutions Do Now 9/29: Take out homework (3-1 worksheet) so I can check it. You have 5 minutes (and just 5) to do some quick studying for the quiz: Elements, atoms, compounds, molecules Parts of an atom 3 Types of atomic bonds

Solution: one substance dissolved in another

Solvent: The (liquid) substance that does the dissolving Solute (pronounced Sahl-yoot): The dissolved substance Solvent Solute

Hydrophilic substances “love water” and dissolve easily

Hydrophobic substances “fear water” and don’t dissolve easily

Concentration: How much of something is dissolved in solution The Dead Sea, in the Middle East, has the highest concentration of salt of any body of water on Earth. The solubility of a substance measures the maximum amount that can dissolve. A saturated solution can’t dissolve any more solute.

The golden rule: “Like dissolves like” Solvents are best at dissolving substances that are similar to themselves Water is polar, and is good at dissolving polar compounds. Non-polar solvents (like paint thinner or gasoline) are good at dissolving non-polar substances (like tar or oil) Hydrophilic compounds: polar or non-polar?
