Question

why pure water is a bad conductor

Answer 1

This conducts electricity because it contains some dissolved calcium and magnesium salts, which are good conductors of electricity. ... Water is a good conductor of electricity whereas the distilled water is bad conductor of electricity because it does not contain salt and minerals.

Answer 2

Pure water is bad conductor because it has less ions.Water is a terrible conductor of electricity. Pure water is actually a good insulator. However, water is a great ionic solvent: liquid in which ionic compounds can dissolve easily. It's those dissolved ions that can conduct well - and when water contains many dissolved ions, those ions make a good conducto
