Which level on the pH scale is considered more acidic?

The pH scale measures the acidity or alkalinity of a solution, ranging from 0 to 14. A pH level of 7 is considered neutral, which is the level of pure water at 25 degrees Celsius. Levels below 7 indicate increasing acidity, while levels above 7 indicate increasing alkalinity.

When a solution has a pH lower than 7, it contains a higher concentration of hydrogen ions (H+), which is a defining characteristic of acids. For example, a pH of 1 is highly acidic, while pH values approaching 7 become less acidic. Thus, any pH value that falls below 7 signifies a more acidic environment compared to neutral or alkaline solutions. Therefore, a pH level below 7 is indeed recognized as more acidic.
