Pure water itself is a covalent compound. A covalent compound is always non-electrical.

Water that can act as a conductor usu. has impurities in it...it is therefore a solution (a mixture).

Water with salt (an ionic compound) added to it can act as a conductor due to the conductivity of salt (sodium chloride).
Seawater is one of the e.g.

Water with ethanoic acid added is also a good conductor. Weak acid(carboxylic acid) can conduct...

Pure water is a very bad conductor of electricity but the water which having some salt is better conductor than pure water

Yes, they are right it is not a conductor because there is no ions that will carry the electricity flow. But if the voltage across it will exceed the dielectric breakdown voltage of the water then it will conduct and become a conductor.

Pure water is a covalent compound. It exists as simple discrete molecules and have a simple molecular structure. Hence, it does not exist as ions. Therefore, pure water cannot conduct electricty due to the absence of mobile ions and electrons.

One instance that water can conduct electricity is when there are dissolved substance in it. Only then will water dissociate into hydrogen ions and hydroxide ions. The presence of mobile ions enables it to conduct electricity.

H2O or pure water does not conduct electricity.

1. For electricity to flow, it needs free flowing electrons like those in metals which have sea of electrons.
2. Pure water do not have "extra" electrons since it is stable.

If you want to make water conduct, try ionizing it by dissolving some compounds like salt. That should do the trick.

it's a liquid meaning it would make a fire if it made electricity copper is a good conductor of electricity
