Unit 6
chemistry vocab
term | Answer |
---|---|
pH | hydrogen ion concentration |
Titration | method used to determine the concentration of a 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+ | Hydronium |
Molarity | Number of moles of solute in one liter of solution |
Molality | 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. |
Acid | proton donors that yield hydronium ions in water solution |
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 nonelectrolyte 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 pure solvent and a solution of a non electrolyte in that solvent, and is directly proportional to the molal concentration of the solution. |
Kf | Molal Freezing point constant |
Kb | Molal Boiling point constant |
Buffer | solutions that are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications |
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 a base react to form a salt. |
pOH | hydroxide ion concentration |
