Question:

Write the half cell reaction that took place in the copper electrode?

zinc-copper voltaic cell

Answer:

yeah, just the opposite of zinc- copper is the cathode, so it reduces Cu2+ + 2e- = Cu
ok so first the 0.5 reactants is the only that produces the end result which s the electroplatment And the states factors of the ions is the two formerly or after the reaction so state the STATE (liquid,stable gasoline yaknow )
The zinc-copper voltaic cell is made up of two metals connected by a conductor. Each metal is immersed in a solution of its own ions. The solutions in turn are in contact with each other most likely through some kind of a salt bridge, thus completing the circuit. According to the Table of Activity Series for Metals, zinc is more reactive than copper. It means that when the combination of zinc and copper is used, zinc atoms will tend to get oxidized (lose electrons) to become zinc ions, while copper ions will tend to become reduced (gain electrons) to become copper atoms. Therefore, the reaction at the copper electrode will involve copper ions (Cu^2+) gaining two electrons each and becoming copper atoms (Cu^0) and depositing themselves on the copper electrode: Cu^2+(aq) + 2 e^- → Cu^0(s)
