Detailed Solution

:
Concept: A solution splits into positive and negative ions when an electric current is supplied to it. When an electric current passes through a conducting fluid, chemical reactions take place. As a result, gas bubbles will begin to form on the electrodes.
William Nicholson, a British scientist, produced the initial scientific finding about the chemical effects of electric current. He had shown that forcing current through electrodes while they were submerged in water caused oxygen and hydrogen bubbles to develop. While the electrode linked to the battery's negative terminal contains hydrogen molecules, the electrode connected to the positive terminal produces oxygen bubbles.
This phenomenon is referred to as the chemical action of electric current. On occasion, the solution's colour will also change. The electrodes and solution that are used make a significant difference.
Assume that water's constituents divide into positive and negative ions when it is subjected to an electric current. These ions will permit the passage of an electric current. Pump well and pond water is contaminated because it contains a variety of dissolved minerals. This water is good at conducting electricity as a result. Distilled water conducts electricity poorly because there are no dissolved salts in it.
Hence, the correct answer is option 2.
