Answer
The blood pH for this blood is equal to 7.10.
Work Step by Step
1. Calculate the pKa value for carbonic acid:
$pKa = -log(Ka)$
$pKa = -log( 7.9 \times 10^{- 7})$
$pKa = 6.10$
2. Use the Henderson-Hasselbalch equation:
$pH = pKa + log(\frac{[Base]}{[Acid]})$
$pH = 6.10 + log(10)$
$pH = 6.10 + 1.00 = 7.10$
