A pH less than 7 is considered which?

Explanation:
The concept being tested is how pH reflects acidity or basicity in a solution. A pH scale measures hydrogen ion activity: the lower the pH, the higher the hydrogen ion concentration. When pH is less than 7, there are more H+ ions than in pure water, so the solution is acidic. At pH 7 the solution is neutral, and above 7 it becomes basic (or alkaline). Therefore, a pH below 7 is considered acidic. The other terms don’t fit because basic/alkaline describe pH above 7, and neutral describes pH equal to 7.
