In this reaction, zinc atoms each will lose two electrons (oxidation) and become Zn 2 + ions. The two electrons that are released by zinc will be gained by the Cu 2 + ions (reduction). The Cu 2 + ions become Cu atoms.. Total equation: Zn (s) + CuSO 4 (aq) --> Cu (s) + ZnSO 4 (aq)

For the half-reaction "Cu"^(2+)(aq) + 2e^(-) -> "Cu"(s), 2 electrons are involved for every 1 copper atom, so in the Nernst equation E_(cell) = E_(cell)^@ - (RT)/(nF) lnQ, we have that n = "2 mols e"^(-)/"1 mol Cu"^(2+), while the … WebScience Chemistry When copper (II) sulfate pentahydrate (CuSO4·5 H2O) is heated, it decomposes to the dehydrated form. The waters of hydration are released from the solid crystal and form water vapor. The hydrated form is medium blue, and the dehydrated solid is light blue. The balanced equation is: Heat CuSO4·5 H2O (s) -------> CuSO4 (s) + 5 ...
WebAs Cu 2+ has higher reduction potential than H +, it gets preferentially reduced. 2Cu 2++4e −→2Cu. At anode (oxidation): As OH − has higher oxidation potential than SO 42−, it gets preferentially oxidised. 4OH −→2H 2O+O 2+4e −. Hence, Cu at cathode and O 2 at anode are produced by electrolysis of aqueous CuSO 4 with inert electrodes.
