1. Suppose you want to deposit silver on an iron spoon using silver nitrate as electrolyte. Which terminal of the battery should you connect the spoon to?
2. Boojho has done the activity of electroplating a spoon with copper. After that he interchanged the connection of the copper plate and the spoon. What will now Boojho observe?
3. Paheli while performing an electroplating activity observed that copper is deposited to the negative terminal of the battery. Boojho tried to repeat the same experiment but could find only one copper plate. Therefore he used a carbon rod as a negative electrode. Will copper be still deposited on the iron rod? Explain.
4. The above circuit was set up for purification of zinc. What will be the nature of (i) plate A (ii) plate B
(iii) the solution. Explain the process of purification.
5. Why is zinc better than tin for electroplating a piece of iron in order to prevent it from rusting?
