कॉपर के विद्युतलेपन की प्रक्रिया में, जब कॉपर सल्फेट विलयन में विद्युत धारा गुजारी जाती है, तब

1. Copper sulphate dissociates into copper ions and sulphate ions
   
   कॉपर सल्फेट; कॉपर आयनों तथा सल्फेट आयनों में वियोजित हो जाता है
2. The free copper ions get deposited to the electrode connected to the negative terminal of battery
   
   स्वतंत्र कॉपर (तांबा) आयन, बैटरी के ऋणात्मक टर्मिनल से संयोजित इलेक्ट्रॉड पर निक्षेपित हो जाते हैं
3. The free sulphate ions get deposited to the electrode connected to the negative terminal of battery
   
   स्वतंत्र सल्फेट आयन, बैटरी के ऋणात्मक टर्मिनल से संयोजित इलेक्ट्रॉड पर निक्षेपित हो जाते हैं
4. Loss of copper from solution gets compensated by dissolving the copper rod connected to the positive terminal of battery
   
   विलयन से कॉपर की हानि की क्षतिपूर्ति बैटरी के धनात्मक टर्मिनल से संयोजित कॉपर छड़ के घुलने से हो जाती है
