Final answer:
The blood pH can be calculated using the formula pH = -log[H+], and for a hydrogen ion concentration of 6.18×10⁻⁸ M, the pH is approximately 7.21.
Step-by-step explanation:
To calculate the pH of a solution when given the concentration of H+ ions, you can use the formula pH = -log[H+]. In this case, the concentration of H+ in the blood is found to be 6.18×10⁻⁸ M.
Plugging in the given hydrogen ion concentration into the pH formula:
pH = -log(6.18×10⁻⁸)
Using a calculator, you can find that the pH of the blood is approximately 7.21.
This pH value is within the normal range for blood pH, which is typically between 7.35 and 7.45, indicating that the blood is slightly more acidic but still close to the neutral pH.
