The OH ion concentration of a blood sample is 2.5 x 10-7 M. What is the pH of the blood?

Sagot :

Solution:

Step 1: Calculate the pOH of a blood sample.

[tex]\text{pOH} = -log[\text{OH}^{-}][/tex]

[tex]\text{pOH} = -log(2.5 × 10^{-7})[/tex]

[tex]\text{pOH} = 6.60[/tex]

Step 2: Calculate the pH of a blood sample.

[tex]\text{pH} = 14 - \text{pOH}[/tex]

[tex]\text{pH} = 14 - 6.60[/tex]

[tex]\boxed{\text{pH} = 7.40}[/tex]
