8.2 to 8.9
Incorrect Answer6.0 to 6.2
Incorrect Answer7.0 to 7.8
Correct Answer9.3 to 9.6
Incorrect AnswerExplanation:
- Option 1: 8.2 to 8.9
- This range is too alkaline for human body function. Human blood and cells cannot survive in this range.
- Option 2: 6.0 to 6.2
- This is too acidic for the body. The human body would not function well and major organs could fail.
- Option 3: 7.0 to 7.8
- This is the right range. Human blood pH is normally about 7.35–7.45. Slight deviations can cause health issues, but generally, the body manages to keep within this range.
- Option 4: 9.3 to 9.6
- This is much too alkaline. At this pH, proteins in the body could denature and critical systems would fail.
