Pure water at normal atmospheric pressure freezes at 00C / 320F. A fifty percent mixture of table salt (NaCl) and water freezes at a considerably lower temperature, -180C / 00F. Due to the additional heat losses necessary to reach this lower temperature, and therefore the extra time needed to lose this energy, salt water does not freeze more quickly than pure water.

Another popular myth perpetuated by people who are impressed more by sensationalism than by fact, is that hot water freezes faster than cold water. This is also not true.
