salt water electrolyzation

Does the amount of salt in salt water affect it's ability to electrolyse?

Yes chlorine will be evolved in preference to oxygen. The salt will improve the conductivity of the solution so it will electrolyse faster, but you will get chlorine, not oxygen, and chlorine is nasty stuff - used as a chemical weapon in the first world war. Epsom salts - magnesium sulphate, or even a little dulute sulphuric acid is a much nicer thing to add as you will get oxygen out.
