What is the pH range of an alkaline solution?

The pH scale measures the acidity or alkalinity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, which means that any solution with a pH higher than 7 is classified as alkaline. Therefore, the range for an alkaline solution is from above 7 to 14, confirming that the appropriate answer encompasses the full scope of what defines an alkaline solution. This includes various substances that are commonly found in both everyday products and in different environments, such as cleaning agents and natural waters that can show alkaline properties. Understanding this range is crucial for professionals working with hazardous materials or in situations where chemical reactions are involved, as it aids in handling and using these substances safely.
