The water does not conduct electricity Bashny.Net

Everyone knows that water and electricity - a very dangerous combination. However, by itself does not make the water current. Then why water is considered a good conductor?

To understand this, it is necessary to introduce an atom which is composed of protons, neutrons and electrons. The ratio of neutrons and electrons determine the charge of the atom. If the number of protons is greater than the electron charge is positive, if the opposite - negative. Since the atoms tend to charge neutrality, they give or take electrons. In the transition of an electron from a negatively charged atom to atom with a positive charge generated electricity.

Because water molecules have no charge, then they do not conduct electricity. Therefore, distilled water is considered an insulator, that is, it does not conduct current. However, this water is uncommon. All the water that flows from the tap, is contained in rivers, lakes and seas, - a mineral solution of a particular concentration. It contains both positively (calcium, magnesium, sodium, iron) and negatively (chlorine, sulfate, carbonate) charged particles, however, such water is well-conducting, and the better, the higher the concentration of mineral salts.
