PLEASE HELP:
Combine the two following standard reduction potentials, and write the balanced reaction.Which compound will be oxidized, and which will be reduced? Which compound is considered the electron acceptor?
(each is given as oxidized + e-> reduced)
Acetaldehyde + 2H++ 2e-> Ethanol
S + 2H++2e-> H2S
Homework Answers
*Combined reaction :
Acetaldehyde + H2S --> Ethanol + S (reaction is balanced)
*An electron acceptor, accepts electrons transferred to it from another compound. It is an oxidizing agent because it accept electrons and is itself reduced in the process. Therefore, acetaldehyde is electron acceptor here.
