poor conductor of electricity is rain water ,distilled water , river water, sea water
Answers
DISTILLED WATER AS IT DID NOT HAVE IONS AND MINERALS AND FOR PRODUCTION OF ELECTRICITY IONS ARE REQUIRED . SO DISTILLED WATER IS A BAD CONDUCTOR OF ELECTRICITY
sea water is the best conductor of ELECTRICITY
Sea water has a lot of salt. This salt then dissociates, into ions, which make the fluid more conductive.
The ions are what carry electricity in fluids.
Seawater can make those ions quicker than a normal liquid.
Pure water is a poor conductor of electricity while fresh water or tap water may be said to be a modest conductor and salt water has a much higher conductivity than fresh water.
The electrical conductivity of water, both pure water and water with dissolved salts, is simpler to measure than to explain. Conductivity of water does not work like conductivity in a metal. In a metal, the outer electrons of the metal atoms are not tightly bound to specific atoms but rather distributed widely and are pretty much free to move in response to an electric field. When you apply a voltage to a metal you get a large flow of electrons.
In water, the application of a voltage results in the movement of charge, but the charges are not nearly-free electrons but rather ions (charged atoms or molecules). In pure water, the ions that are moving are the protons in the form of H3O+ and hydroxide ions, OH-. In other ionic solutions it is the dissolved ions themselves, for instance in salt water, sodium chloride dissociated into the ions Na+ and CL-.
This shows that distilled water does not conduct electricity. Dissolve a pinch of common salt in distilled water. When salt is dissolved in distilled water we get salt solution. ... Thus, distilled water becomes a good conductor of electricity on dissolving a little of salt in it.
hope this helps u ❤️
