Question

Compare and contrast what happens when electricity is passed through distilled water and tap water respectively?

Answer 1

Answer:

Concerning water droplets, a good quality distillation column can minimise their quantity and improve steam quality to almost 100 percent. If you need high purity water, the usual procedure is to deionise distilled water as DI - as explained before - does not remove non-ionic (e.g. organic) species.

There is a difference between high purity DI water and simple DI water. The latter is more "soft" only than tap water; it might even have a greater conductivity than distilled (or double distilled) water.
