Question : Within what pH range does the human body work?
Option 1: 8.2 to 8.9
Option 2: 6.0 to 6.2
Option 3: 7.0 to 7.8
Option 4: 9.3 to 9.6
Correct Answer: 7.0 to 7.8
Solution : The correct answer is 7.0 to 7.8 .
Living things depend on even minute changes in pH range to survive. The human body functions within a range of 7.0 to 7.8 degrees. The wide range of pH values is too much for the human body to handle. Acidity is defined as a pH of less than 7. Alkaline or basicity is also indicated by a pH value greater than 7.
