If pure water is an insulator how can it be demonstrated or proved ?

It can be proved simply--if you have a "clean room".
If you take distilled water in a sterilized, clean container and simply put two sterilized, clean leads from an ohmmeter into it it will register almost infinite electrical resistance. But, eventually contaminants from the air/environment will get into the water causing electrical conductivity.

Do you mean an electrical insulator, or a thermal insulator?
If you're talking about an electrical insulator, then put two ends of a battery terminal on opposite ends of the inside of a tank of water. If the battery doesn't drain, then water is an insulator.

It is not a great conductor, but it is not an insulator. Plus, water is a fair solvent and quickly becomes contaminated, so that it is usually a pretty fair conductor, no matter how it started out.
The test for this is fairly simple. Put electrodes from a voltage meter in a beaker, add pure water, then add a contaminate in small increments to see the result.
Wee.

If your talking about an electrical insulator, then yes. It is the minerals dissolved in water that conduct electricity. Pure water is a very poor conductor.

Use an ohmeter and measure it. Infinite ohms (insulator, over 10 Megahoms or higher) or conductor (a few ohms, AFTER you've zeroed the meter to compensate for the copper test leads)

Water is not a good insulator

Measure it's resistance with an ohm meter. A cheap multimeter from Radio Shack will work. You will find that salty water has low resistance, tap water high resistance and distilled water has very high resistance. In fact, the resistance of water is used as a measure of it's purity in the semiconductor industry.

get the foll. thimgs
1)'5' volt power supply
2)Beaker containing ur pure water with two carbon electrodes
3)connecting wires
4) A low power LED
now connect above things in series& on the circuit
if LED glows even slighty then it's not insulator
in above expt.u can use use highly sensitive galvanometer instead of LED

Insulator? When I wore my jacket made of water it didnt keep my very warm. Not at all really, wow. That was a bad investment. O...Regret.

Its electrical conductivity must zero.it mean it will not conduct electricity so pure water will work as a insulator (no any traces of salt )
