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.
A substance made from two or more elements in definite proportions. eg NaCl
Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure 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
Table salt is NaCl, which is named sodium chloride.
NaCl pure is also colorless at room temperature.
pure substance...since it is NaCl...a compound..
Pure solide NaCl is not electrically conductive. The water solution of NaCl is an electrolyte and is conductive.
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.
The answer is 0,9 g pure, dried NaCl.
No NaCl has nearly pure ionic bond
Pure and dried salt (NaCl) has no salt.
