Question:
What is the ideal pH of the blood and most body fluids?



Replies:
The normal concentration of hydrogen ions in the body fliuds is 4 X 10-8 or translated into pH is 7.4. Range can be between 7.0 and 7.8 in extreme conditions.

The pH of human blood is 7.35 to 7.45. Most parts of the body are also this pH except the stomach which is about 3 and the intestines which are about 8. The urine is slightly acidic usually in order to help keep the blood at the proper pH.
