Is pure water a semi conductor?

No. The flow of electrical current in water is caused by the flow of charged ions in the water to the +ve and -ve terminals in the water.

In pure water there are no dissolved ions - so no current. If (for example) you dissolve common salt (sodium chloride, NaCl) in water the salt splits into Sodium ions (Na+) and Chloride (Cl-). these ions will then be able to move in the water - so salt water will conduct electricity.

Is pure water an electrical conductor?

At a high enough voltage, everything is an electrical conductor. Pure water is an exceptionally bad electrical conductor, though.


Which is a poor conductor tap water or pure water?

Pure water is a poor conductor of electricity because of the lack of ions. You need ions (electrically charged particles) to propagate the charge through the water. Both tap and pure water are poor conductors of heat.


Is water a insulator o a conductor?

"Pure water" is an insulator, but real water has impurities which if ionized make it a conductor.


Is water a conductor or non conductor?

100% Pure water is not a conductor (insulator) However, please remember, minerals in not 100% pure water are conductors and there are about 10 million minerals in 1 cup of water. It can electrify you. So becareful.


What is extrinsic conductor?

Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .


Is water a conductor of electricty?

Yes and no. Pure water, i.e. distilled or deionized, is a very poor conductor of electricity. However, in most cases water is not pure and has some amount of dissolved ions making it a good conductor.


How would you classify water as an electrical conductor?

Pure water is a insulator, however if there are ions in the water it becomes an excellent conductor.


What is the conductivity of pure water?

Pure water is a poor conductor of electricity due to its low concentration of ions.

Is water a better conductor of electricity than human body?

Pure water hardly conducts electricity at all. You have to dissolve a lot of stuff in pure water to make it as good a conductor as the human body is.
