Salt, or sodium chloride, is a mineral that naturally occurs in the seas and in underground deposits. It is an ionic chemical compound with the formula NaCl. This means that for every gram of salt, almost 40 per cent (39.337%) is sodium (Na) and over 60 per cent (60.663%) is chlorine (Cl). Where does our salt come from?
