Here are the essential concepts you must grasp in order to answer the question correctly.
pH Scale
The pH scale measures the acidity or basicity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, values below 7 indicate acidity, and values above 7 indicate basicity. Understanding the pH scale is essential for classifying substances as acidic, basic, or neutral.

Acids and Bases
Acids are substances that donate protons (H+) in a solution, while bases accept protons. This definition is rooted in the Brønsted-Lowry theory, which helps categorize substances based on their chemical behavior. Knowing the characteristics of acids and bases is crucial for determining the nature of a given substance.

Drain Cleaner Composition
Many drain cleaners contain strong bases, such as sodium hydroxide (lye), which contribute to their high pH levels. A pH of 11.2 indicates a basic solution, which is typical for drain cleaners designed to dissolve organic matter. Recognizing the common components of drain cleaners aids in understanding their chemical properties.
