Is blood an acid or alkali?

Answer 1

The normal pH value of human blood is about 7.4, which is very slightly on the alkaline side.

Blood is slightly basic, generally having a pH of about 7.4. The range it must maintain is between 7.0 and 7.8 or acidic coma or tetany ensues and the human dies.

The pH value of blood is 7.35 - 7.45 which is just a tiny bit higher than neutral 7.00 so very weakly basic.

However blood is NOT a pure substance but a mixture of (among others) weak acidic and weak basic and neutral ions, molecules and ... and cells (red, white, ...) ... etc.

Answer 2

Blood is slightly alkaline, with a normal pH range of about 7.35 to 7.45. This means that it is slightly basic, not acidic. The body carefully regulates the pH of blood to maintain proper function of cells and enzymes.
