Its pH is about 6.5.

Explanation:

The pH of any fluid is measured by the hydrogen ion concentration. A pH of 7 is neutral, pH of below 7 is acidic, and above 7 is basic in nature.

The variety of factors such as lung function, kidney function, endocrine function, vomiting, diarrhea, and urinary tract infection affects the pH of the blood. So, the normal blood pH is slightly alkaline in nature and regulated between 7.35-7.45.
