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]

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
