An aqueous sodium chloride solution for use in production of caustic soda in an electrolytic cell having a cation exchange membrane is purified by adding to said solution a chemical reagent for precipitation separation of impurities remove silica through co-precipitation with a slurry of the precipitates of impurities which are circulated through said solution.
A good method of refining NaCl is repeated crystallization/recrystallization.
Generally the solution is refined by repeated processes of crystallization/recrystallization.
Refining of sodium chloride is realized by repeated processes of crystallization/recrystallization.
Salt can be refined by the filtering of the water solution and repeated processes of crystallization/recrystallization.
It commonly involves dissolving the salt in water and then filtering and cooling down to recrystallize. Other purification techniques may also be used.

How made pure salt?
A good method of refining NaCl is repeated crystallization/recrystallization.
What are pure compounds?
A substance made from two or more elements in definite proportions. eg NaCl
Is salt a combination of 2 pure substances?
Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure substances
Are HCl aq NaCl aq HCl g and NaCl s substances?
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
What is the name given to the substance that pure table salt is made from?
Table salt is NaCl, which is named sodium chloride.
Why NaCl turns colourless when melted?
NaCl pure is also colorless at room temperature.
Is salt mixture or pure substance?
pure substance...since it is NaCl...a compound..
Why is there difference in conductivity between 5 percent NaCl solution and pure NaCl?
Pure solide NaCl is not electrically conductive. The water solution of NaCl is an electrolyte and is conductive.
Which of the following are pure elements MgCl2 NaCl C3H8 Ag Al?
Pure elements are substances made up of only one type of atom. Among the options given, Ag (silver) and Al (aluminum) are pure elements. MgCl2 and NaCl are compounds made up of multiple elements bonded together, while C3H8 is a hydrocarbon molecule made up of carbon and hydrogen atoms.
How many grams of nacl would you use to make 100ml of 0.9 percent nacl?
The answer is 0,9 g pure, dried NaCl.
Does Na-Cl have a pure covalent bond?
No NaCl has nearly pure ionic bond
Which will have the lowest boiling point pure water 0.5 M NaCl aq 1.0 M NaCl aq or 2.0 M NaCl aq?
Pure water will have the lowest boiling point because it does not contain any solute particles to elevate the boiling point. As the concentration of NaCl increases, the boiling point also increases due to an increase in the number of solute particles that disrupt the formation of water vapor. Therefore, 0.5 M NaCl will have a higher boiling point than pure water, followed by 1.0 M NaCl, and finally 2.0 M NaCl will have the highest boiling point.
