Salt is added to increase the conductivity of water, because pure distilled water is very difficult to conduct electricity, can generally be seen as an insulator!
The added salt depends on the salt! The laboratory does not use distilled water for electrolytic water test, but distilled water with a small amount of dilute sulfuric acid or sodium hydroxide mixture, that is, sulfuric acid or sodium hydroxide dilute solution, the concentration is very low, generally not more than 2%! Very few laboratories add salt to water, but they don't, but they do n' t add sodium chloride, sodium bromide, etc. Because electrolysis doesn't produce oxygen! Add sodium chloride and the electrolysis produces chlorine, hydrogen and sodium hydroxide!
