Sodium Chloride From Water

Introduction to Sodium Chloride from water:

Sodium Chloride is an ionic compound with its IUPAC name as Sodium Chloride and

Common names as common salt, saltex, halite, table salt, rock salt, saline, hypo saline, sodium mono chloride, sodium chloric.

It is represented by NaCl. It is major ingredient in edible salt, and is commonly used for adding flavor to the complement food and also used food preservatives.

Sodium Chloride is a very good conductor of heat and electricity. Also, because of the ionic bonds formed between sodium and chlorine, sodium chloride dissolves in water.

Methods to separate sodium chloride from water:


There are various methods to separate sodium chloride from water. Some of them are as follows:-

1.Evaporation
Evaporation is a process of continuous heating of any liquid till that point when all the liquid gets evaporated. It is considered as the natural removal of water from the solution at relatively low temperature. So, for separating sodium chloride from water, the process of evaporation is used. So, in it when the water evaporates away, and the salt remains in the container. Then, it is separated away from the water. But, it's a slow method of separation of sodium chloride from water.

2.Distillation
Other method to separate sodium chloride from water is distillation. Distillation means to boil the water out of the solution as steam. By doing so, the salt will remain in the container (distillation flask) while the water can be collected in another flask. The steam can be condensed if required to produce pure water(known as desalination).Distillation is used commercially to produce large quantities of pure water from sea water for industrial and domestic use in areas where natural fresh water is not readily available. As in desert regions etc. This however is done as a continuous process and the sea water is flowing through the distillation unit leaving the outlet flow with more salt in it as some of the water is distilled off. The process is also carried out under high vacuum to decrease the boiling temperature of the sea water to about 65°C, thereby reducing the heat input.).

Having problem with convert fahrenheit to celsius formula keep reading my upcoming posts, i will try to help you.

Conclusion for separation of sodium chloride from water:


From the above we can conclude that sodium chloride can be separated from water by two methods: distillation and evaporation.
