What is the normal pH of blood?

  1. 6.8

  2. 7.0

  3. 7.4

  4. 8.0

The correct answer is: 7.4

The normal pH of blood is slightly basic, ranging from 7.35 to 7.45. Option A and D have pH levels that are outside of this range, making them incorrect. Option B is very close, but not entirely accurate. It is important to remember that the human body has a very narrow pH range for optimal functioning, and any significant deviation can lead to health issues.
