Inorganic salts are compounds consisting of ions held together by ionic bonds, without the presence of carbon-hydrogen (C-H) bonds. These salts are essential for various physiological processes, like maintaining electrolyte balance in the body, regulating nerve and muscle function, and supporting cellular and metabolic functions. Common examples include sodium chloride (table salt), potassium iodide, and calcium carbonate. These salts are obtained through diet and are critical for maintaining proper bodily functions and health.
