Q
Define:
Buffer
A
A solution consisting of either a weak acid or a weak base that can resist pH changes upon the addition of acidic or basic compounds
2
Q
What does the pKa and Ka of a buffer tell you?
A
The range it preserves
3
Q
Biological systems tend to buffer around pH -
A
7
4
Q
What is blood buffered by? Describe how
A
Bicarbonate
1. CO2 lowers pH
2. HCO3- increases pH
5
Q
State:
The formula for pH based on the pKa and acid/base concentrations
A
pH = pKa + log([acid]/[base])
