properties of solutions
| Question | Answer |
|---|---|
| another name for a solution | homogeneous mixture |
| part of solution that is mixed in | solute |
| part of solution that does the mixing | solvent |
| solutions have this number of phases | 1 |
| solution dissolving more than max amount of solute | super saturated |
| solution dissolving less than max amount of solute | unsaturated |
| solution dissolving exactly the max amount of solute | saturated |
| determines if substance will dissolve in solvent | composition of solute and solvent |
| can affect the rate of dissolving | temperature , stirring , surface area of solute |
| only state of matter where solubility is affected by pressure | gases |
| states of matter where solubility is affected by temperature | solids , liquids, gases |
| when liquids mix in ALL amounts | miscible |
| when liquids DO NOT mix in ANY amounts | immiscible |
| SI unit for amount of substance | mole (mol) |
| SI unit for mass | kilograms (kg) |
| non-SI unit for volume | liters (L) |
| moles of solute / L of solution | molarity (M) |
| moles of solute / kg of solvent | molality (m) |
| law: S1/P1 = S2 / P2 | Henry's |
| solution with small amount of solute | diluted |
| solution with large amount of solute | concentrated |
| fix for a diluted solution | add more solute |
| fix for a concentrated solution | add more solvent |
| defined area in a mixture | phase |
| property based on amount of solute particles (not type) | colligative |
| mL (g) of solute / mL (g) of solution x 100% | percent by volume |
| measure of amount of solute that dissolves in specific amount of solvent that creates a saturated solution | solubility |
| freezing point depression , boiling point elevation , vapor pressure lowering | 3 examples of colligative properties |
| affects solubility of solids, liquids and gases | temperature |
| only affects the solubility of gases | pressure |
