Question

Identify the chemical effects of electric current from the following.

• A. Change in colour of the solution.
• B. Deposition of metal on electrodes.
• C. Evaporation of chemicals.
• D. Formation of bubbles of gas on the electrodes.

Answer 1

Answer: (A), (B), (D)

The correct options are
A Change in colour of the solution.
B Deposition of metal on electrodes.
D Formation of bubbles of gas on the electrodes.

The passage of an electric current through a conducting solution causes chemical reactions. Some of the chemical effects of electric current are:

• Formation of bubbles of gas on the electrodes.
• Deposition of metal on electrodes.
• Change in colour of solutions.
