The pH scale measures acidity or alkalinity. pH less than 7 is acidic, pH greater than 7 is alkaline (or basic), and pH 7 is neutral. - Bananas have a pH of (acidic). Therefore, blood is the only substance among the options that is not acidic; it is slightly alkaline.

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.
