What pH level is defined as acidic?

A pH level that is defined as acidic is any value that is less than 7. This range signifies an excess of hydrogen ions in the solution, leading to increased acidity.

In the context of pH, a scale ranging from 0 to 14 is used, where 7 is considered neutral, representing pure water. Values below 7 indicate acidity, while values above 7 indicate alkalinity or basicity. The closer the pH value is to 0, the more acidic the solution is.

Understanding pH levels is particularly important in fields such as agriculture and horticulture, as the acidity of the soil can influence nutrient availability and overall plant health. Certain crops thrive in acidic soils, while others may require more neutral or alkaline conditions.

Knowing that anything under 7 corresponds to acidic properties helps in managing soil health and determining suitable pesticide applications tailored to specific environmental conditions.
