Lecture 4 Flashcards
1
Q
pH equation using [H+]
A
pH = -log [H+]
2
Q
What is the normal range of [H+] in the body?
A
38nm - 42.7nm
3
Q
How does a pH change of about 0.3 when pH is around 7 correspond to the change in [H+]?
A
It corresponds to about a 2-fold change in [H+]
4
Q
What is the normal pH range for blood?
A
7.37 - 7.42
5
Q
Equation for Ka
A
Ka = [H+][A-]/[HA]
6
Q
Equation for pKa
A
pKa = -log Ka
7
Q
Equation for pH using pKa
A
pH = pKa + log [A-]/[HA]
8
Q
What is the normal pCO2 range?
A
35 - 45mmHg
9
Q
What is the normal [HCO3] range?
A
22 - 26 mM
10
Q
How are acidosis/alkalosis characterized?
A
When there is deviation beyond the normal ranges for pCO2 and [HCO3], which are 35 -45mmHg and 22 - 26mM respectively
11
