1

pH equation using [H+]

pH = -log [H+]

2

What is the normal range of [H+] in the body?

38nm - 42.7nm

3

How does a pH change of about 0.3 when pH is around 7 correspond to the change in [H+]?

It corresponds to about a 2-fold change in [H+]

4

What is the normal pH range for blood?

7.37 - 7.42

5

Equation for Ka

Ka = [H+][A-]/[HA]

6

Equation for pKa

pKa = -log Ka

7

Equation for pH using pKa

pH = pKa + log [A-]/[HA]

8

What is the normal pCO2 range?

35 - 45mmHg

9

What is the normal [HCO3] range?

22 - 26 mM

10

How are acidosis/alkalosis characterized?

When there is deviation beyond the normal ranges for pCO2 and [HCO3], which are 35 -45mmHg and 22 - 26mM respectively

11

Henderson equation

[H+] = 23.9 pCO2/[HCO3]
