Term | Definition |
---|---|
acid | proton donors that yield hydronium ions water solution |
base | proton acceptors identified by release of hydroxide ions |
boiling point elevation | the difference between the boiling points of the pure solvent and a non electrolyte solution of that solvent and is directly proportional to the molal concentration of the solution |
buffer | solution that are used as a means of keeping pH at a nearly constant value in a wide variety o chemical applications |
collagative properties | depend on the concentration of solute particle but not on their identity |
concentration | the amount of solute in a given amount of solvent in a solution |
dissociation | the seperation of ions that occur when an icocnic compound dissolves |
electrolyte | a substance that dissolves in water to give the solution the ability to conduct electricity |
end point | the point in a titration at whcih no more titrant should be added. it is determined for example by a color change in an indicator or by the appearannce of a precipitate |
freezing point depression | the difference between the freezing points of the pure solvent and a solution of a non electrolyte in that solvent and is directly proportional to the molal concentration of the solution |
H3O+ | hydronium |
Kb | molal boiling point constant |
Kf | molal freezing point constant |
molality | the concentration of a solution expressed in moles of solute per kilogram of solvent |
molarity | number of moles of solute in one liter of solvent |
neutralization | a chemical reaction in which an acid and a base react to form a salt |
pH | hydrogen ion concentration |
pOH | hydroxide ion concentration |
solubility | the capability to dissolve |
titration | method used ton determine the concentration of a substance in a solution |
