It walk seem favor water have the right to conduct electricity and also that is why us shouldn’t touch any electrical outlet or switches if our hands are not dry.
You are watching: Why doesn t distilled water conduct electricity
Does water really conduct electricity?
Let’s discover out by doing a straightforward controlled experiment.
In this experiment, friend will find out that pure water doesn’t command electricity, but conductivity increases if friend mix salt, street or other impurities in the water.
Does Water Conduct power Experiment
Materialssmall LED diode2 tiny button batteriescopper wires or electric wires v alligator clipsscotch tapetap waterdistilled water (you deserve to use bottled people or make your very own distilled water)
InstructionsFill the tiny container with tap water.Dip the two open ends into the water.Now, repeat the experiment using the exact same setup, but this time, instead of using tap water, use distilled water.Using madness water, girlfriend should be able to complete the circuit and also the LED pear lights up.
Why go water command electricity and why doesn’t water conduct electricity
Acontrolled experimentis a test done double with exactly the very same conditions and also variables except for one.
That one varied aspect is referred to as anexperimental control.
In this exercise, water is the speculative control.
Everything rather in the experiment stay the same.
So we can conclude the the distinction in the result is led to by the control, i.e. The water.
So insanity water can conduct power while distilled water cannot.ExploreDo the experiment again byadding saltinto the purewater and also see if the LED pear lights up.It should.The LED bulb may also be brighter 보다 the one utilizing tap water since salt water conduct electricity far better than madness water does.Do the experiment again byadding sugarinto pure water.This time, the LED bulb does no light up since sugar cannot contribute ions to the solution.

An electric existing is carried out by aflow of electrical charges such as electrons or ions.
Pure water has very couple of ions and so it is a negative electricity conductor.
But as soon as impurities such as salt or sugar dissolve in water, the result solutionconducts electricity an extremely well.
Tap water is such a solution.
Most water we come into call with, such as tap water or notcompletely distilled party water, save impurities that revolve water into a conductor.
That is why you have to NOTtouch electric outlets or switches through wet hands.

But not all impurities deserve to do so, only those the can contribute ions, such as salt.
