Metallic sodium, in an atmosphere of chlorine gas, would burn very vigorously, producing NaCl. Of course, salt is a very abundant compound in our world, so it would never actually be necessary to produce it by this method.
NaCl---------------→Na+ + Cl-
The equation is: NaCl----------Na++ Cl-
Na+ + Cl- --> NaCl NaCl = salt.
Sodium and chlorine can be separated from NaCl by electrolisys.
NaCl --> Na+ + Cl- You could write water on either side I suppose, but it is negligible. I've also seen H2O written over the arrow.
The percentage of chlorine in NaCl is 60,33417 %.
The oxidation number of Na in NaCl is +1, while the oxidation number of Cl in NaCl is -1.
It is 0.22M also. moles refers to an amount of molecules OR atoms (i.e. ions)
Sodium chloride is dissociated in water: NaCl------------------Na+ + Cl-
An example is the dissociation of NaCl in water: NaCl (s) -> Na+ (aq) + Cl- (aq). Here, NaCl breaks apart into its constituent ions, Na+ and Cl-, when dissolved in water due to the attraction between the ions and water molecules.
58 g NaCl = 58 (g) / 58.44 (g/mol NaCl) = 0.9925 (mol NaCl) = 0.9925 (mol Cl-) = 0.9925 * 35.45 (g/mol Cl-) = 35.2 g Cl-
NaCl is added to water when a saline water solution is necessary; NaCl is dissociated in water: NaCl -------------------Na+ + Cl-
