Pure water itself is an insulator of electricity whereas water containing particles like salt , is a very good conductor of electricity .

Pure water's particles are closely packed together , thus no other form of energy can pass through .
In salt water , the salt particles are dissolved in the pure water .
The salt particles are not so closely packed together .
Hence , the electricity is able to flow through only water containing small soluble solids .

Is water a conductor of electricity?

Pure water is not a conductor of electricity but with impurities,e.g.sail,sugar,it is a conductor of electricity.So we must not touch any electrical appliances with wet hands!!!

Is water a conductior of electricity?

Very pure water is a very bad conductor of electricity, but even tiny amounts of ionic impurities can make it conduct. Seawater, for example, conducts electricity well.

IS WATER A GOOD CONDUCTOR OF ELECTRICITY???????

pure water is an insulator while water containing salt is good conductor of electricity.ok that's all bye bye!!!!!!!!!!

Is water a conductor of electricity?

Pure water is not a conductor of electricity.
But if it has the slightest amount of salt or mineral solids,
then it will be a conductor of electricity.

Is Water A Conductor Of Electricity?

Water is a conductor of electricity if something,like etc:salt is added in. Pure water is not a conductor of electricity.

sorry dear readers,whohave read wat i have written.pure water is an insulator while water containing salt is a good conductor of electricity

is water a conductor of electricity?

Q:is water a conductor of electricity?
Ans:yes.
why?:water is a conductor of electricity because there is minerals in water.the lesser the minerals the water will be a bad conductor.minerals and gases was readily dissolve in water. It is the presence of this minerals and gases that allows water to conduct electricity. Perfectly pure water without these impurities will not conduct electricity but salt water is a good conductor of electricity.beacause salt is a mineral thus making salt water a good conductor.

Is water a conductor of electricity?

Water itself is not a conductor of electricity. In order for a substance to carry charge, two conditions must first be met:
1.There must be charged particles within the substance (either ions or electrons) and
2.These particles must be free to move It is true that in water (H2O) the discrete molecules are free to move, however, they carry no charge. The only reason water can sometimes conduct electricity is because of the minerals (metallic solids)

Is water a conductor of eletricity?

Question:Is water a conductor of electricity?
Answer:Yes . Water is a conductor of electricity and most of the liquid other than water are also conductors of electricity.

Is water conductor of electricity?

Pure water cannot conduct electricity. However, the presence of the smallest amount of salt in water enables water to become an electrical conductor.

Is water a conductor of electricity???

Pure water is an insulator of electricity, but even tiny amounts of ionic impurities can make it conduct. Seawater, for example, conducts water very well.Only impure water,ie. water that contains ions,will conduct electricity,as to why H2O does not break into the H ions and OH ions and then conduct electricity.

Is water a conductor of eletricity?

Pure water is an insulator.
Only impure water, ie. water that contains ions, will conduct electricity, as to why H2O does not break into the H ions and OH ions and then conduct electricity, to be honest, I don't yet know. But I suspect that the electrons flowing through are not vibrating at the correct frequency to excite the electrons that hold the two ions together to break apart.

Does water CONDUCT electricity and WHY??????

Hi guys,


Electricity is defined as the flow of electrons.
Getting water pure enough to not conduct electricity is very hard to do.
There are lots of minerals and gases that readily dissolve in water.
(Even if you have pure water, carbon dioxide from the air will immediately
begin to disslove into the water). It is the presence of these minerals
and gases that enable water to conduct electricity. The impurities in the
water is what is conducting electricity. You should know by now that salt
water is an excellent conductor of electricity. Table salt, or sodium
chloride, dissolves in water to form an "ionic" solution composed of
sodium ions and chloride ions. In an ionic solution such as this, the
chloride ions have a greater affinity for electrons than the sodium ions,
thus the flow of electrons between the sodium and chloride ions is easy,
thus electricity can be conducted in salt water. Pure water
has "covalent" bonds between the hydrogen and oxygen molecules. This
means there is an equal sharing of the elecrons within the molecule itself
and it does not have an affinity for electrons. So pure water does not
conduct electricity where as impure water will.

Greetings~♥
come on to read the uber-nice 12th issue of peanut times!!! as agreed, i will talk about children's day, but as you know, homework is priority 1st on the amazing GarethRocks list, so shaddup and listen.. or read, i guess. Is water a conductor of electricity? ( ZAPPEROOO!! lols) Pure water is an insulator.

well, that was amazing! A common asked question by adults: why celebrate children's day when our children are practically the one's causing our high blood pressure, low poo production, high containance of undigested food, low urine production... what was i saying?! well, basically, adults, we are somehow ur life. we are the generation of tomorrow!!! Quotation " R.E.M the next generation" We are very important, okay!! please ask more questions about this in the comment box. i will try my best to answer.

hey!! lets make fun of history!! Stamford Waffles!! Bread-itiam, Kopitalk( breadtalk) if you have any other funny historical stuff, send them to me at 81937531.

Is Windows a Virus


No, Windows is not a virus. Here's what viruses do:
1.They replicate quickly - okay, Windows does that.
2.Viruses use up valuable system resources, slowing down the system as they do so - okay, Windows does that.
3.Viruses will, from time to time, trash your hard disk - okay, Windows does that too.
4.Viruses are usually carried, unknown to the user, along with valuable programs and systems. - Sigh.. Windows does that, too.
5.Viruses will occasionally make the user suspect their system is too slow (see 2) and the user will buy new hardware. - Yup, Windows does that, too. Until now it seems Windows is a virus but there are fundamental differences: Viruses are well supported by their authors, are running on most systems, their program code is fast, compact and efficient and they tend to become more sophisticated as they mature. So Windows is not a virus. It's a bug.

The poem corner
Grounded
Alone in my room, is where I will sit,
never before had I thrown such a fit.
stories and stories, I lied through my teeth,
hoping for a glimpse at a sign of relief.
They pushed and they pushed, until I gave in,
by now I should know that I never will win.
then came the punishment, for what I had done,
whatever it is it shall not be fun.
Everything's gone, no seeing nice weather,
for these next two weeks are gunna feel like forever.
With nothing to do, god forbid I should read,
but that's what they want, never follow their lead.
Just staring at walls, my but falls asleep,
there is nothing but silence not even a peep.
My TV is off, but I see people moving,
no bother to me it's actually quite soothing.
What am I saying? I think I've gone mad,
it's only three days and my life's already sad.
Every second goes by like a month or a year,
why don't they realize I'm dying in here?
Someone come get me before I go crazy,
I should use the excuse,"This is making me lazy"!
"Knock-knock" what is that? you say that it's over,
why I got up and plowed like a freak'n bull dozer.
The moral of this story is that crime doesn't pay...
and never mop the floor with your grandpa's toupee

and that is all for today, so bye!! keep a look out on the trafic, because... there are traffic lights. so stay tuned to the ghostly, ghastly 13th isse of the peanut times where everything gets ghostly!! this is reporter Gareth signing off~~~

well,first answer this question.y do we gey electricuted when we get in contact with plugs and sockets when our hands are wet?then u will know the answer.[something to do with a close circuit]

ways to prevent ourselves from being electricuted

1)Keep your hands dry before removing a socket.
2)when you need to remove a wire without a non-conductor covering, wear a rubber glove.
3)Do not allow water to be near plugs.
4)Do not poke things which are conductors of electricity into socket holes.
