A pH reading of 6.0 in raw water indicates what type of sample?

• A. Basic
• B. Neutral
• C. Acidic
• D. Contaminated

Answer: (C)

A pH reading of 6.0 in raw water indicates an acidic sample. The pH scale ranges from 0 to 14; values below 7 are considered acidic, with 7 being neutral, and values above 7 being basic (or alkaline). Since a pH of 6.0 is below the neutral point of 7, it means that the water has an excess of hydrogen ions, which is characteristic of acidic conditions. Thus, a pH reading of 6.0 signals that the water may need treatment to adjust its acidity, especially if it's intended for drinking water standards, as water with a higher acidity can lead to corrosion of pipes and infrastructure and may affect the aquatic life in the source.
