The Minnesota Pollution Control Agency (MPCA) says statewide about 404,000 tons of road salt are used every year.

The structure on the right has one sodium chloride molecule for every 13 water molecules, and is stable only at high pressure.

The positive areas of the water molecules surround the negative Chloride ions. The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

Elements bond in fixed ratios and so can be represented by a chemical formula. For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl ...

Sodium chloride is an ionic compound. The table shows some limitations of different models for sodium chloride.
