What does nonacidic mean?
Nonacidic means that something does not have an acidic reaction or composition. In practical terms, it may describe a substance whose pH is neutral or above 7, or soil that is not acid enough to harm certain plants. The word is especially useful in science, agriculture, chemistry, environmental studies, and product descriptions, where distinguishing acidic conditions from neutral or alkaline ones is important. It is the direct opposite of acidic, but it is not always exactly synonymous with alkaline: a nonacidic substance can be neutral rather than distinctly basic. The prefix non- is attached to acidic, and the word may appear with or without a hyphen depending on style and usage.
adjectiveNot acidic; having a neutral or alkaline reaction rather than an acidic one.
- Having no acidity; being neutral or alkaline.

"The gardener tested the soil to determine whether it was nonacidic before planting the seeds."
Nonacidic is more than the opposite of acidic: it can describe anything from neutral soil to an alkaline solution.
