Term | Definition |
solute | the component that is dissolved in solution |
solvent | the component in which a solute is dissolved |
miscible | capable of being mixed |
immiscible | incapable of being mixed |
molarity | moles of solute/ 1 liter of solution |
solubility | a measure of how much solute that will dissolve in a solvent at a given temperature and pressure |
dissolution | the process of dissociating a solute into smaller molecules or ions |
solvation | the process of solvent particles surrounding the solute particles in solution |
ionize | to dissociate compounds into cations and anions |
electrolyte | any substance that ionizes when dissolved |
strong electrolyte | completely dissociates when dissolved |
weak electrolyte | partially dissociates |
non-electrolytes | does not dissociate |
unsaturated | less than saturated |
saturated | exists at the equilibrium where the rate of dissolution = rate of recrystallization (maximum amount of solute is dissolved for the particular temp and pressure) |
supersaturated | more than saturated (sodium acetate) |
molality | moles of solute/ 1 kg of solution |
like dissolves like: | the role of polarity in solubility (oil is non-polar, water is polar- both do not dissolve) |
how do molal boiling & freezing point constants for electrolytes differ? (boiling salt water lab) | the boiling point elevation is proportional to the molality of the solute particles |
if 2 solutions have the same concentration but one is salt water and the other is sugar water, will they have the same boiling point? or will one be higher than the other? which one? why? | |
colligative properties | depend on the concentration of the solute but not the identity of the solute |
how can a titration be accurate? | A titration is an analytic method that determines the precise endpoint of a reaction and therefore the precise quantity of reactant in the titration flask |
why do the titration graphs look alike? | because they will all have a similar equivalence point that will fall in-between a similar point |
