Culinary<unk>  is a common agent in food processing and cooking.<unk> ng is used to preserve or season the food.<unk> ng can be applied to vegetables, cheeses and fruit in a process known as pickling. Meat and fish are typically steeped in<unk>  for shorter periods of time, as a form of marination, enhancing its tenderness and flavor, or to enhance shelf period. Chlorine production Elemental chlorine can be produced by electrolysis of<unk>  (NaCl solution). This process also produces sodium hydroxide (NaOH) and Hydrogen gas (H2). The reaction equations are as follows: * Cathode: 2 H+ + 2 e- -> H2 (^) * Anode: 2 Cl- -> Cl2 (^) + 2 e- * Overall process: 2 NaCl + 2 H2O -> Cl2 + H2 + 2 NaOH Refrigerating fluid<unk>  is used as a secondary fluid in large refrigeration installations for the transport of thermal energy. Most commonly used<unk> s are based on inexpensive calcium chloride and sodium chloride. It is used because the addition of salt to water lowers the freezing temperature of the solution and the heat transport efficiency can be greatly enhanced for the comparatively low cost of the material. The lowest freezing point obtainable for NaCl<unk>  is at the concentration of 23.3% NaCl by weight. This is called the eutectic point. Because of their corrosive properties salt-based<unk> s have been replaced by organic liquids such as polyethylene glycol. Sodium chloride<unk>  spray is used on some fishing vessels to freeze fish. The<unk>  temperature is generally . Air blast freezing temperatures are or lower. Given the higher temperature of<unk> , the system efficiency over air blast freezing can be higher. High-value fish usually are frozen at much lower temperatures, below the practical temperature limit for<unk> . Water softening and purification<unk>  is an auxiliary agent in water softening and water purification systems involving ion exchange technology. The most common example are household dishwashers, utilizing sodium chloride in form of dishwasher salt.<unk>  is not involved in the purification process itself, but used for regeneration of ion-exchange resin on cyclical basis. The water being treated flows through the resin container until the resin is considered exhausted and water is purified to a desired level. Resin is then regenerated by sequentially backwashing the resin bed to remove accumulated solids, flushing removed ions from the resin with a concentrated solution of replacement ions, and rinsing the flushing solution from the resin. After treatment, ion-exchange resin beads saturated with calcium and magnesium ions from the treated water, are regenerated by soaking in<unk>  containing 6–12% NaCl. The sodium ions from<unk>  replace the calcium and magnesium ions on the beads. De-icing In lower temperatures, a<unk>  solution can be used to de-ice or reduce freezing temperatures on roads.
