Boojho observed that copper is deposited …

What Vishal Kumar said For your kind information and not a hacker I just saw the last answer and there was her/his name

No, copper will not be deposited on the carbon rod used as a negative electrode in the experiment. This is because the deposition of copper on the electrode is a result of the reduction of copper ions present in the solution onto the electrode. The reduction of copper ions occurs at the negative electrode, which attracts the positively charged ions towards it. However, for the deposition of copper to take place, the electrode used as the negative terminal should be made of a material that has a lower reduction potential than copper. Copper has a reduction potential of -0.34 V, which means any electrode with a reduction potential lower than -0.34 V can be used as the negative electrode. Carbon has a reduction potential of -0.22 V, which is higher than the reduction potential of copper. This means that carbon is not a suitable material for the negative electrode in this experiment, as it cannot attract the copper ions from the solution and reduce them to form a copper deposit. Therefore, even if Paheli uses a carbon rod as the negative electrode, copper will not be deposited on it as it does not have a lower reduction potential than copper.
