Which statement correctly describes the pH of acidic wastewater?

Explanation:
Understanding pH and acidity is the key idea. The pH scale runs from 0 to 14, where lower values are more acidic, 7 is neutral, and higher values are more basic (alkaline). Acidic wastewater is defined by having a pH below 7, so the statement that pH less than 7 indicates acidity is the correct one. A pH of 7 is neutral, not acidic; a pH above 7 is basic, and a very high pH like 12 is strongly basic, not acidic. Maintaining appropriate pH helps prevent corrosion, protects treatment processes, and ensures discharge limits are met.
