Acidosis
|
a serious condition that results in oxygen deprivation
|
|
Buffers
|
contain significant amounts of both a weak acid and its conjugate base, enabling the buffer to neutralize added aicd or added base
|
|
A buffer works best when
|
-the amounts of acid and conjugate base it contains are large and approximately equal.
-if the relative amounts of acids and base differ by more than a factor of 10, the ability of the buffer to neutralize added acid and added base diminishes |
|
The maximum pH range at which a buffer is effective is
|
one pH unit on either side of the acid's pKa
|
|
Polyprotic acid
|
an acid that contains more than one ionizable proton and releases them sequentially
|
|
Titration curve
|
a graph of the change in pH versus added volume of acid or base during titration
|
|
solubility product constant, Ksp
|
-an equilibrium constant for the dissolution of an ionic compound in water
-constant at a given temperature |
|
reaction quotient, Q
|
the ratio, at any point in the reaction, of the concentrations of the products of a reaction raised to their stoichiometric coefficients to the concentrations of the reactants raised to their stoichiometric coefficients
|
|
Selective precipitation
|
a process in which an added reagent forms a precipitate with one of the dissolved cations but not others
|
|
Qualitative analysis
|
-a systematic way to determine the ions present in an unknown solution
-operates on the principle that a mixture of cations can be seperated and analyzed based on the differences in the solubilities of their salts |
|
Quantitative analysis
|
-a systematic way to determine the amounts of substances in a solution or mixture
|
|
Complex ion
|
contains a central metal ion coordinated to two or more ligands
|
|
Formation constant (Kf)
|
the equilibrium constant associated with reactions for the formation of complex ions
|
|
Ligand
|
a neutral molecule or an ion that acts as a Lewis base with the central metal ion in a complex ion
