Question

Which of the following will conduct electricity?
(A) Distilled water
(B) Potable water
(C) Well water
(D) None of the above

Answer 1

Hint: Impure and salty water will conduct electricity but pure water can’t not be able to conduct electricity due to absence of ions.
Water is a conductor of electricity if it is salty or impure because impure water contains minerals such as sodium, calcium, magnesium etc. These minerals are containing charged ions.

Complete step by step solution:
> For anything to lead power, it needs portable charge bearers: particles that are allowed to move inside the material and have an electrical charge that makes them move because of an applied electrical field. In metals, the versatile charge transporters are electrons, which are so approximately held to the particles that they can without much of a stretch move about. In non-metallic substances by and large, and explicitly in water, the electrons are firmly held to the particles and are not allowed to move about. The atoms can move, yet having no net electrical charge they don’t move in light of electrical fields: they feel no power that makes them relocate toward some path. In this manner water doesn’t lead to power. (Unadulterated water does unexpectedly separate into positive hydrogen particles and negative hydroxide particles, however just to a brief degree: just around 2 atoms in a billion are ionized along these lines at some random time.
Basically, ions are carrying electrical charge which can be produced by the removal of electrons or addition of electrons to some natural atom which can be either positive or negative.
> Due to the presence of these charged ions, electricity is able to flow through the water which is impure(minerals). On the other hand, pure water does not contain impurities, so in pure water there are no charged ions, so electricity is not able to flow in pure water.
> According to this we can say that impure water is a good conductor of electricity and pure water is a good insulator (bad conductor). But if we add salt or sodium chloride in pure water, so pure water converts into impure water now it will also be a conductor of electricity.
Reason: when sodium chloride or salt dissolve into water it breaks into charged ions.
                               \[{H_2}O\, + \,NaCl \to N{a^ + } + C{l^ - } + {H_2}O\]
These are some examples of conductors of electricity tap water, well water, sea water etc.

The correct answer is C.

Note: Naturally there is no pure form of water except distilled water, so avoid taking the risk of water and electricity flow experiments, because very few impurities can flow electricity in water due to charged ions in it.
