Detailed Solution

Chemical effect of electric current can be explained through an experiment with iron nails immersed in salt water and connected to the battery.
Chemical effect of electric current:
When an electric current is passed through a conducting solution, chemical reactions occur in the solution. This is the chemical effect of electric current. One of the chemical effects of electric current is: Gas Bubbles are formed at electrodes.
The chemical effect of electric current can be explained when Iron nails are immersed in salt water and connected to the battery.
Take two iron nails and clean them by rubbing them with sandpaper. Immerse them in water with a little salt. Connect them to a battery and close the circuit. Small gas bubbles are seen on the nails. This is because an electric current breaks water into hydrogen and oxygen. This observation shows the Chemical effect of electric current on water.
