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 |
