Solution
The passage of an electric current through a solution causes chemical effects.
Explanation:
The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes in the colour of solutions may occur. The reaction would depend on what solution and electrodes are used. These are some of the chemical effects of the electric current.
