How to make water stop conducting electricity?

Everyone knows that water conducts electricity well. For this reason, for example, you should not swim in thunderstorm, you should not work with electrical appliances with wet hands, and so on. But does water actually conduct electric current?

In fact, it is not water that conducts electricity, i.e. not water molecules, but various impurities contained in it, in particular ions of various mineral salts. Water is an excellent solvent, therefore, in nature, many different impurities are always dissolved in water, which lead to the fact that water in its natural state on Earth always conducts electricity.

But modern technologies make it possible to completely purify water from all impurities, if necessary, leaving only the molecules of the water in it. Water purified from impurities is called distilled water. So distilled water almost does not conduct electric current, but is a good dielectric instead. Distilled water is widely used in engineering, medicine and industry and is produced in large quantities. You can even buy it at car dealerships and pharmacies.

However, do not rely too heavily on the fact that the water is purified and therefore must not conduct electricity. The fact is that distilled water requires special handling; otherwise it will dissolve many impurities in itself very quickly and become a conductor again. So in everyday life you will not be able to keep the water so clean for too long that it does not conduct electricity.

All this means that safety measures when working with electrical appliances and devices still cannot be violated. Remember that the water that you can find in everyday life always has impurities and therefore is a good conductor of electric current.
