Redox tables and nonmetals
« on: June 09, 2011, 05:25:13 PM »
I am given the following information and asked to construct a redox table.



Here is what I came up with for the redox table. I am unsure if it is correct because my textbook doesn't really give examples that include nonmetals like this question.

Br2(aq) + 2e-  ::equil:: 2Br-(aq)
Ag+(aq) + e-  ::equil:: Ag(s)
I2(aq) + 2e-  ::equil:: 2I-(aq)
Cu2+(aq) + 2e-  ::equil:: Cu(s)

Is any of this right?

Technically all these equations are OK.

IMHO it will be better to write them all as either oxidation or reduction - doesn't matter much which, just be consistent. I would go for reduction.

Not sure what you mean by "redox table" - I guess you are expected to arrange them according to redox potentials.

Thanks for the confirmation. The textbook I am using explains the redox table as a table of relative strengths of oxidizing and reducing agents in the form oxidizing agent + ne-  ::equil:: reducing agent, with the strongest oxidizing agent at the top left and strongest reducing agent at the bottom right of the table. Like in the equations I posted.

I am an idiot, these are all reduction reactions, no idea what I was thinking about. Let's call it a senior moment  :-\
