Q19Long answer
In the circuit given as Fig. 14.7, Boojho observed that copper is deposited on the electrode connected to the negative terminal of C HEMICAL EFFECTS O F ELECTRIC CURRENT 83 the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore she took a carbon rod as negative electrode. Will copper be still deposited on the carbon rod? Explain your answer. Fig. 14.7
This question refers to a figure in the original PDF.
Show answer
Yes, copper from the copper sulphate solution will be deposited on the carbon rod. Copper from the copper plate will be dissolved into the copper sulphate solution for electroplating.
