Detailed explanation-1: -Answer and Explanation: Biologically-active compounds such as enzymes and nucleic acids in plants, animals, and humans have optimum pH of 7. At this pH level, they function properly and efficiently.
Detailed explanation-2: -The reference point on this scale is pure water, with a pH of 7 at 25 degrees Celsius.
Detailed explanation-3: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Detailed explanation-4: -Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.
Detailed explanation-5: -pH is measured on a scale of 0 to 14. On this scale, a pH value of 7 is neutral, which means it is neither acidic nor basic. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more basic.
