Question

Does pure water conduct electricity?
A. Yes
B. No
C. Sometimes
D. none of the above

Answer 1

Hint: The presence of salts such as sodium chloride in the solution is responsible for the conduction of the electricity. The conduction of the electricity will depend on the components which are present in the water.

Complete step by step solution:
- In the given question, we have to tell whether pure water can conduct electricity or not.
- As we know that water is a colourless, tasteless and odourless inorganic compound which is made up of two hydrogen molecules and one oxygen atom.
- It is commonly said that tap water can conduct electricity whereas pure or distilled water cannot.
- This is due to the presence of the different types of ions in the tap water such as sodium, potassium calcium, copper, etc.
- When the electrode with negative and positive is kept in the tap water the negative and positive salt ions separate due to which the conduction of electricity takes place.
- Whereas in the case of distilled water, the water is treated in which the ions present in the water are separated.
- Due to which there is the absence of salt ions in the pure water and hence, no conduction of the electricity will take place.

Therefore, option A is the correct answer.

Note: Copper is the element which has a high conductivity power due to which it is used in the wiring of the electric wires. The positive ions present in the water are potassium, magnesium, etc whereas the negative ions are carbonate, chloride, etc.
