Introduction

Table salt, also known as common salt or refined salt, is the most widely used form of edible salt in households and food preparation. It consists primarily of sodium chloride (NaCl) and is typically highly refined, meaning that it has been purified to remove most minerals and impurities. Commercial table salt is often iodized, meaning it has added potassium iodide or potassium iodate to prevent iodine deficiency, a public health measure introduced in many countries in the 20th century.

Table salt is characterized by its fine, uniform crystal size, which allows for easy and precise measurement, rapid dissolving, and even distribution in food. It may contain anti-caking agents such as calcium silicate, magnesium carbonate, or sodium aluminosilicate to prevent clumping in humid environments. Its primary culinary uses include seasoning, preservation, and baking, where exact measurements are often required.
