Term | Definition |
---|---|
pH | hydrogen ion concentration |
Tritration | method used to determine the concentration of substance in a solution |
Dissociation | The separation of ions that occur when an ionic compound dissolves |
Electrolyte | A substance that dissolves in water to give the solution the ability to conduct electricity |
Base | proton acceptors identified by release of hydroxide ions |
H3O+ | Hydroponic ion |
Molarity | Number of moles of solute in one liter of solution |
Molatity | The concentration of a solution expressed in moles of solute per kilogram of solvent |
Colligative Properties | Depend on the concentration of solute particles but not on their identity |
Concentration | The amount of solute in a given amount of solvent in a solution |
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 |
Freezing Point Depression | The difference between the freezing points of the pre-solvent and a solution for a non-electrolyte in that solvent, and is directly proportional to the molal concentration of the solution |
Solvation | the process of dissolving |
Buffer | solutions that are used as a means of keeping pH at a nearly constant value in a wide variety of chemical appliction |
Solubility | The capability to dissolve |
End point | The point in a titration at which no more titrant should be added It is determined, for example, by a color change in an indicator or by the appearance of a precipitate |
Neutralization | a chemical reaction in which an acid and base react to forma salt |
pOH | hydroxide ion concentration |
OH- | Hydroxide ion |
