Why is tap water is a good conductor of electricity?

Posted by Yuv Raj 7 years, 9 months ago

1 answers

Yogita Ingle 7 years, 9 months ago

Presence of salts in the water makes it good conductor electricity. If water does not contain any salts (or impurities) then it is considered to be pure water, this does not conduct electricity. So, saline water or sea water is a good conductor while tap water or distilled water is a bad conductor of electricity.

Yogita Ingle 7 years, 9 months ago

The process of depositing a thin layer of a desired metal over a metal object with the help of electric current is called electroplating.
Electroplating is done for
1)Protection from corrosion
2)Testing for decorative purpose
For example : Bathroom taps made of iron or steel are electroplated with chromium metal to prevent their corrosion or rusting. It gives a shining appearance to the bathroom taps due to which they look more attractive. The metal objects are usually electroplated with chromium, nickel, silver ,gold or copper metals.

This is due capillary action. It is explained as the rise in water in narrow air spaces and tubes without assistance of external forces and also in resistance to external forces such as gravity. This is the force that makes the water rise in a straw in a vessel filled with a liquid.
