1.	A current of `2.68 A` is passed for `1.0` hour through an aqueous solution of `CuSO_(4)` using copper electrodes. Which of the following statements is `//` are correct ?
Answer» The electrode reaction are : `underset("1 mole")(Cu^(2+))+ underset(2xx96500 C)(2e^(-)) rarr Cu ("Cathode")` `Cu rarr Cu^(2+)+2e^(-) ("Anode")` Thus, cathode increases in mass as copper is deposited on it and the anode decreases in mass as copper from it dissolves. Charge passed through cell `=2.68xx60xx60` coulomb Copper deposited or dissolved `= 63.5/(2xx96500)xx2.68xx60xx60=3.174 g` Increase in mass of cathode = Decrease in mass of anode `=3.174 g`
