The problem
http://www.chem.iastate.edu/group/Greenbowe/sections/projectfolder/animations/CuZncell.html
After veiwing the animation found at the website above answer these questions:
Is there an electron transfer between species?
Which species is losing electrons
Which species is gaining electrons?
Write down the oxidation half reaction under the species that is undergoing oxidation.
Write down the reduction half reaction under the species that is undergoing reduction.
What is the Anode?
What is the Cathode?
Which direction is the spontaneous reaction? Explain your reasoning.
Write the complete balanced equation for the reaction.
2.The attempt at a solution
Is there an electron transfer between species? Yes
Which species is losing electrons? Zinc/Zn
Which species is gaining electrons? Copper/Cu
Write down the oxidation half reaction under the species that is undergoing oxidation. Zn-> Zn 2+
Write down the reduction half reaction under the species that is undergoing reduction. Cu 2+ ->Cu
What is the Anode? Zinc/Zn
What is the Cathode? Copper/Cu
Which direction is the spontaneous reaction? Explain your reasoning.
The spontaneous reaction is occurring from the zinc to the copper because the zinc is losing electrons and the copper is gaining electrons.
Write the complete balanced equation for the reaction.
Zn 2+ + Cu --> Cu 2+ +Zn
Please help me here!
I need someone to check my answers, I'm pretty sure about the first ones, but the last one about the balanced equation I think it wrong.
Any help would be greatly appreciated.
THANKS!
