moles per liter. Find the pH value of human blood. Is human blood acidic or​ basic?




The pH value is calculated using the formula:

\[
pH = -\log[\text{H}^+]
\]

where \([H^+]\) is the hydrogen ion concentration in moles per liter. 

Given:
\[
[H^+] = 4.58 \times 10^{-8}
\]

Now, let's calculate the pH:

\[
pH = -\log(4.58 \times 10^{-8})
\]

We can split the calculation into two parts:
\[
pH = -\log(4.58) - \log(10^{-8}) 
\]

\[
pH \approx -0.661 - (-8) = 8 - 0.661 = 7.339
\]

### Conclusion:
The pH of human blood is approximately **7.34**, which means the blood is slightly **basic** (since a pH above 7 indicates a basic solution).

**Tip**: Small changes in pH can have significant effects, as the pH scale is logarithmic.

The hydrogen ion concentration [H+] of blood is approximately 4.58 × 10^-8 moles per liter. Find the pH value of human blood. Is human blood acidic or basic?

Calculate the pH of human blood given a hydrogen ion concentration of 4.58 × 10^-8 moles per liter. Using logarithmic properties, find out why the pH is approximately 7.34 and what it means for the blood to be slightly basic. Suitable for high school students in Grades 9-12.
