pH Scale Guide
Understanding the pH Scale
The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 are acidic, while values above 7 are basic (alkaline).
Acidic (0-6)
Examples: lemon juice, vinegar, battery acid
Neutral (7)
Examples: pure water, blood
Basic (8-14)
Examples: baking soda, soap, bleach
Frequently Asked Questions
What is pH?
pH is a measure of the hydrogen ion concentration in a solution, indicating how acidic or basic it is. The scale ranges from 0 to 14, with 7 being neutral.
How do I interpret pH values?
Values below 7 are acidic, 7 is neutral, and values above 7 are basic (alkaline). Each whole number represents a tenfold change in acidity or alkalinity.
What is pOH?
pOH is the negative logarithm of the hydroxide ion concentration. It complements pH, and their sum always equals 14 in water at 25°C.
Why is pH important?
pH is crucial in many fields including chemistry, biology, medicine, agriculture, and industry. It affects chemical reactions, biological processes, and product quality.
Important Notes
- pH values range from 0 to 14, with 7 being neutral
- Values below 7 indicate acidic solutions
- Values above 7 indicate basic (alkaline) solutions
