1
Q
Buffered solutions reduce….
A
pH fluctuations
2
Q
Adding an acid and conjugate base into a solo will be both a _______________ and a ________.
A
- defined conc. of buffer
- specific pH
3
Q
Henderson-Hasselbalch
A
used to determine pH of a given acid/base mix or correct mix to produce a desired pH
4
Q
H+H equation
A
pH=pKa+log[conj.base]/[acid]
5
Q
If pH is < pKa
A
-more acid
6
Q
If pH is > pKa
A
-more basic
7
Q
Both the amino and carboxyl ends of an amino acid can act as…
A
acid/conj.base pair
8
Q
At low pH, both ends amino and carboxyl ends are…
A
protonated and charge is +1
9
Q
At high pH, both ends amino and carboxyl ends are…
A
deprotonated and charge is -1
