How do you know when a reduction reaction that contains H+ or OH- can be included as the SOA or SRA?
This question pretains to Chemistry 30, Electrochemistry. I have a question on an assignment that wants me to list all the entites in reaction, the SOA, the SRA, if the reaction is spontaneous, and (if it is spontaneous) the half reactions for the SOA and SRA as well as the net reaction. The question states that, "aqueous silver nitrate and solid copper metal" are present in the chemical reaction.
I was told that if a question does not specifically specify acidic or basic conditions, I cannot use a reducation reaction on the redox table that has H+ or OH-. So for this reaction, I would assume the SOA is Ag+ (aq), and the SRA is Cu (s).
However, I looked up this question to see if this was the correct way to evaluate something like this and saw people were using NO3- (aq) + H+ (aq) as the SOA. And while NO3- (aq) is present in this reaction and a higher oxidizng agent than Ag+, I wrote it off because no where does this system specify acidic conditions, meaning the H+ couldn't be present in the SOA.
Could anyone clarify if my thinking is correct or incorrect, and why?
