Answer 2

Answer:

Pure water is a bad conductor/insulator of electricity because:

• Pure water contains no ions which can conduct electric energy.
• It has no salts, acids and bases in it.
• These chemicals are not in it except it's molecule.

[Note: Pure water is also known as distilled water]

Additional information:-

• Pure water is a bad conductor of electricity but dirty water is a very good conductor of electricity.
• Pure water doesn't contain any other foreign materials except its form. Due to this property, this does't conducts electricity.

HOW CAN WE KNOW THAT A GIVEN QUANTITY OF WATER IS NOT IN ITS PURE FORM??

• Take the given quantity of water in a beaker.
• Collect wires and a 0 watt bulb and make a circuit as given in attachment.
• If the bulb glows, water isn't pure but, if it doesn't, it is ure.

(Note: The battery in the above activity should contain two 9V cells)
