The pH of human blood is normally in the range of 7.35-7.45. is blood basic or acidic? Strongly or weakly?
Homework Answers
pH scale is measured from 0 to 14.
acidity decreases as pH increase from 0 to 7.
pH of 7 is neutral
in the pH range of 7 to 14, basicity increases with 14 being strongly basic
7.35-7.45 can be considered as weaky basic.

Human blood contains a buffer of carbonic acid (H 2CO 3) and bicarbonate anion (HCO 3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. Carbonic acid is about 0.108 percent and the density is 1.67 g/mL. Determine the molarity of carbonic acid in blood.

1. The correct functions of your lungs contribute to the normal pH level of between 7.35 and 7.45 in your blood. If your lungs do not exchange and remove carbon dioxide from your blood, the blood pH will change. A reading of pH 6.4 of your blood indicates: A. no health risk, as part of normal pH changes in your body that in this case bring it closer to neutral pH. B. a health problem due to the concentration of...
