Lab report/Chemistry ? and contrast simple distillation with steam distillation 

2. In a saline/simple distillation, how can we be sure that this is completely deionized? What processes in the distillation proves this?

Thanks for any help y'all!

    Simple distillation is powered by a direct heat source usually of over 100°C. In steam distillation the heat source is steam passing through the medium being distilled. It is therefore usually performed at much lower temperature,

    The advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds like essential oils. 

    how can we be sure that this is completely deionized? .. we test the distillate for conductivity. Pure water does not conduct but if ions are present we see a reading 

    The ions in the saline solution are not volatile so only the water evaporates to be condensed to pure water but the apparatus.
