What is the maximum value on the pH scale?

The maximum value on the pH scale is 14. The pH scale measures the acidity or alkalinity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, with values below 7 indicating acidity and values above 7 indicating alkalinity.

A pH of 14 represents the highest alkaline level, which is typical of very strong bases, such as sodium hydroxide. Understanding the pH scale is essential for various applications, including environmental science, chemistry, and biology, as it helps to determine the chemical properties and behaviors of different substances. Thus, the value of 14 is crucial as it serves as a boundary for strong alkaline solutions.
