Question

give an example with equation showing the chemical reaction that takes place under the influence of electricity.​

Answer 1

Answer:

When an electric current is passed through a conducting solution, some chemical reaction takes place in the solution. This is among the chemical effects of electric current. For example, when some current is passed through water, water ionizes into H+ (aq) and OH– (aq) ions, where H+ (aq) ions go towards the cathode to gain electrons and form H2 whereas  OH– (aq) ions go towards the anode to lose electrons and form O2 molecules.

Some of the chemical effects of electric current are as follows :

• Bubbles of gas may be formed at electrodes.
• Deposits of metal may be seen on electrodes.
• Change of colour of solution may occur.
