Question

Short ans type Questions :- a . How is distilled water different from tap water in terms of electrical conductivity ? b. Dushyant compared the conduction of electricity in rainwater and tap water .Explain his observation. c. Why are bubbles produced around the electrodes when electrodes are immersed in salt solution and electricity is passed? ( spam and irrelevant ans = reported, don't know answering the question = deleting his /her 5 questions )​

Answer 1

Answer:

Required Answer:-

1. When you try to measure the conductivity of tap water you can verify that it has higher conductivity in comparison with distilled water because this contains ions (less pure). The tap water has higher conductivity due to the presence of the ions: Ca2+ and Mg2+.
2. Magnetic needle shows deflection because of conduction of electricity through the solution. We know that when electric current passes through a conductor, the conductor behaves like a magnet. This is called magnetic effect of electric current.
3. Oxygen bubbles formed on the electrode connected to the positive terminal of the battery and hydrogen bubbles formed on the other electrode. The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed on the electrodes.

Answer 2

Explanation:

1.The conductivity of the aqueous solution water/salt is proportional to the ions concentration in the solution. When you try to measure the conductivity of tap water you can verify that it has higher conductivity in comparison with distilled water because this contains ions (less pure).
