1
Q
Common ion effect
A
the presence of a common ion suppresses the ionization of a weak acid or weak base
2
Q
buffer solution
A
a solution that contains significant concentrations of both members of a conjugate acid-base pair
3
Q
The pH at equivalence point of a strong acid-strong base titration is
A
7.00
4
Q
The pH at equivalence point of a weak acid-strong base titration is
A
Above 7.00
5
Q
The pH at equivalence point of a weak base-strong acid titration is
A
below 7.00
6
Q
Solubility product constant (Ksp)
A
is the equilibrium constant that indicates to what extent a slightly soluble ionic compound dissociates in water
7
Q
We can prepare a buffer with a specific pH
A
by choosing a weak acid with a pKa close to desired pH
