What category does salt belong to?

Salt, specifically table salt (sodium chloride), is categorized as an inorganic compound. Inorganic compounds are generally defined as substances that do not contain carbon-hydrogen (C-H) bonds typical of organic molecules. Salts are formed by the electrostatic attraction between positively charged ions (like sodium ions) and negatively charged ions (like chloride ions).

Organic compounds, on the other hand, are primarily made up of carbon atoms along with hydrogen, oxygen, nitrogen and other elements, and they include molecules like carbohydrates, proteins, and lipids. The distinct absence of carbon-hydrogen bonds in salts like sodium chloride is what firmly classifies them as inorganic. Thus, identifying salt as inorganic is the correct classification.
