Sodium Chloride is an alkali halide with an fcc crystal structure ... At elevated temperatures the lattice becomes an ionic conductor, with the major contribution to charge transport from positive ion ...
A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...
The potassium and chloride ions are spectator ions. (see your textbook for a discussion of Lewis Acids and Bases.) From a series of qualitative tests and a microanalysis of this complex formed, you ...
Carbonate ions also produce a white precipitate with barium chloride solution. The acid reacts with any carbonate ions present. This removes them, so stopping them giving a false positive result.
