Question

how will you show experimentally that electric current can bring about a chemical change and a diagram...​

Answer 1

Explanation:

Take water in a beaker and add to it a little salt or a few drops of sulphuric acid to make it conducting.This observation, therefore, shows that electric current has a chemical effect on water. This experiment shows that an electric current can bring about a chemical change. This phenomenon is called electrolysis.

Answer 2

Answer:

Take water in a beaker and add to it a little salt or a few drops of sulphuric acid to make it conducting.Now dip 1 copper string and a zinc string on the opposite sides of the beaker. Now connect the zinc string as negative cathode and copper string as positive cathode.This observation, therefore, shows that electric current has a chemical effect on water. This experiment shows that an electric current can bring about a chemical change. This phenomenon also called as electrolysis.
