What is the pH level that indicates a neutral substance?

• A. 0-6.9
• B. 7
• C. 7.1-14
• D. 6-6.9

Answer: (B)

A pH level of 7 indicates a neutral substance, meaning that it is neither acidic nor basic. The pH scale ranges from 0 to 14, with values lower than 7 representing increasing acidity and values above 7 representing increasing alkalinity. A pH of exactly 7 is defined as neutral, which is the pH of pure water under standard conditions. This is crucial in various contexts, including environmental science and hazardous materials management, as understanding pH helps assess the potential hazards associated with chemical substances and their interactions.
