CHEMICAL SUBSTANCE Meaning and
Definition
-
A chemical substance refers to any form of matter that has a defined composition and distinct properties, resulting from the arrangement of atoms or molecules that comprise it. It can be a pure substance or a mixture of different substances. Chemical substances are fundamental entities in chemistry, and the study of their behavior, properties, and interactions constitutes a significant part of the field.
A pure chemical substance consists of only one type of atom or molecule, and examples include elements like hydrogen, oxygen, or gold, as well as compounds such as water or sodium chloride. Mixtures, on the other hand, consist of two or more substances physically combined, where each component retains its individual identity and can be separated by physical means. Examples of mixtures can range from something as simple as a glass of lemonade to complex mixtures in pharmaceutical drugs.
Chemical substances exhibit specific chemical and physical properties that can be observed and measured. These properties include characteristics such as density, boiling point, melting point, solubility, reactivity, and toxicity, among others. Understanding the behavior and properties of chemical substances is essential for various applications, such as in medicine, agriculture, manufacturing, and environmental studies.
In summary, a chemical substance represents matter with a distinct composition and properties resulting from the arrangement of atoms or molecules. It encompasses pure substances and mixtures, and its study focuses on understanding their behavior, properties, and interactions within the realm of chemistry.

Etymology of CHEMICAL SUBSTANCE
The etymology of the word "chemical substance" can be traced back to its constituent parts: "chemical" and "substance".
The term "chemical" originates from the Medieval Latin word "chemicus", which came from the Greek word "khēmikos". "Khēmikos" referred to someone skilled in the art of chemistry, which in turn came from "khēmia", meaning "alchemy". "Khēmia" ultimately derived from the Egyptian word "kēme", meaning "earth" or "black", alluding to the black soil along the Nile River and the association of alchemy with the transformation of matter.
The word "substance", on the other hand, comes from the Latin word "substantia", which is a combination of "sub", meaning "under", and "stans", meaning "standing".
