Which of the following is an example of a chemical property?

• A. Color
• B. Melting Point
• C. Toxicity
• D. Density

Answer: (C)

Toxicity is indeed a chemical property because it describes a substance’s ability to cause harm or an adverse effect on living organisms through chemical reactions. This property indicates how a substance interacts with biological systems at the molecular level, revealing its potential to cause damage, poison, or other harmful effects when encountered in a specific environment. In contrast, color, melting point, and density are examples of physical properties. Color refers to the visual perception of light reflected from a substance; melting point describes the temperature at which a solid transforms into a liquid; and density measures the mass per unit volume of a substance, reflecting its structural characteristics without indicating how it will chemically react or interact with other materials. Understanding these distinctions helps in identifying qualities of matter in both practical and theoretical contexts in power engineering and chemistry.
