Condenser cooling water with a pH of 10.0 would be considered what?

A pH of 10.0 indicates that the water is above a neutral pH of 7.0, meaning it has a higher concentration of hydroxide ions compared to hydrogen ions. This elevated pH is characteristic of alkaline substances. In the context of water, a pH value greater than 7 indicates that it has properties consistent with an alkaline solution. Therefore, condenser cooling water with a pH of 10.0 is correctly described as alkaline. Being alkaline also implies that it is not acidic, as acidic solutions would have a pH less than 7. Thus, the classification of the water as alkaline accurately reflects its chemical nature.
