What is the pH level of water considered to be alkaline?

Water that is classified as alkaline has a pH level greater than 7. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral, indicating neither acidic nor alkaline properties. As the pH value increases above 7, the solution becomes more alkaline.

A pH of 14 is the maximum on the scale and represents a highly alkaline solution. For example, substances like sodium hydroxide (lye) can have a pH around this value. In practical applications, this knowledge is important for understanding water treatment processes and the overall chemistry of solutions in refrigeration and air conditioning systems, where maintaining proper pH levels can impact equipment performance and longevity.

Thus, identifying a pH level of 14 as alkaline underscores the high degree of alkalinity present at that level, which is essential knowledge for those working in fields where pH management is critical.
