- Human body works in the pH range of: Ans: B The normal pH range of human blood is slightly that correctly encompasses the typical physiological pH range. 160. The desirable range of pH for drinking water is Ans: A pH is a measure of the acidity or alkalinity of water. A neutral pH is 7.0. Water with a pH less than 7 is acidic, and water with a pH greater than 7 is alkaline. The standard recommended range for potable water generally falls within the slightly acidic to slightly alkaline range, as extremely low or high pH can affect palatability, corrosion potential, and the effectiveness of disinfection. 161.
