Question

Which of the following effects can occur on passage of electric current through a conducting solution?

• A. Bubbles of a gas may be formed on the electrodes
• B. Deposits of metal may be seen on electrodes
• C. Change of colour of solutions may occur
• D. All of these

Answer 1

The correct option is D

All of these

The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed at the electrodes. Deposits of metal may be seen on electrodes. Changes of colour of solutions may also occur. The reaction would depend on the nature of solution and electrodes used.
