What is the basic/alkaline range?

• A. 0-5
• B. 8-14
• C. 2-8
• D. No answer is correct

Answer: (B)

On the pH scale, 7 is neutral, and values above 7 indicate basic (alkaline) conditions. The commonly accepted basic range runs from about 8 to 14, with higher numbers reflecting stronger bases. This range distinguishes alkaline water from acidic water (below 7) and helps explain how different species and chemical processes respond to water chemistry, since many aquatic organisms tolerate or prefer neutral to mildly basic conditions, while very high alkalinity can be stressful or harmful.
