how í road salt different from table salt, give the chemicals names and the formula

Answer 1

Road salt, also known as sodium chloride or rock salt, is chemically similar to table salt but usually contains impurities such as calcium and magnesium. The chemical formula of road salt and table salt is NaCl, which means they both consist of one sodium (Na) atom and one chlorine (Cl) atom. However, road salt may also contain trace amounts of other minerals, including potassium and magnesium chloride. The presence of these impurities can make road salt less desirable for consumption and can also be harmful to plants, animals, and the environment.
