Salts are chemical compounds formed by the ionic bonding of positively charged ions (cations) and negatively charged ions (anions). They are created through the reaction of an acid with a base, resulting in the formation of a neutral compound. Salts can take various forms, from crystalline solids to dissolved ions in solution. Common examples include table salt (sodium chloride), Epsom salt (magnesium sulfate), and calcium carbonate. Salts have diverse applications, including as flavor enhancers in food, in chemical processes, as electrolytes in batteries, and in various industrial and biological functions.
