Answer is Right!
Answer is Wrong!
The correct answer is A. 6.5-7.
The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic, while a pH above 7 is basic. Human blood is slightly alkaline, with a pH of 7.35-7.45. This is important because it helps to maintain the proper balance of fluids and electrolytes in the body. If the pH of blood falls outside of this range, it can lead to serious health problems, such as acidosis or alkalosis.
Option B is incorrect because the pH of blood is not between 7.5 and 8. Option C is incorrect because the pH of blood is not between 8 and 9. Option D is incorrect because the pH of blood is not between 4.5 and 5.
