What pH value is indicative of an acid?

Greater than 7
Equal to 7
Less than 7
None of the above

The correct answer is: Less than 7

A pH value of less than 7 is indicative of an acid. The pH scale ranges from 0 to 14, where values below 7 represent acidic conditions, values equal to 7 signify a neutral substance, and values above 7 indicate a basic or alkaline condition. Acids, such as hydrochloric acid or sulfuric acid, typically display a pH between 0 and 7. This relationship is essential in various fields, including chemistry and environmental science, where understanding the acidity of a solution can influence reactions and interactions with other substances. Understanding the pH scale and the characteristics of acids is fundamental for anyone working in hazardous materials management, as many acids can pose significant safety risks and require proper handling and response protocols.
