This is the 2nd problem on a HW sheet I have. I don't have any particular problems with it but I'm just making sure I'm doing these right:(adsbygoogle = window.adsbygoogle || []).push({});

Complete (add H20, H+ or OH- as appropriate) and balance the following equations. Show all half reactions.

a. [tex]NO_3^- + Ag \rightarrow Ag^+ + NO_2[/tex] (acidic)

Half reactions I found to be:

-[tex]Ag\rightarrow Ag^+ + e^-[/tex]

-[tex]e^- + NO_3^- + 2H^+ \rightarrow NO_2 + H_2O[/tex]

making the balanced reaction

[tex] 2H^+ + NO_3^- + Ag \rightarrow Ag^+ + NO_2 + H_2O[/tex]

Any thoughts? I'm pretty iffy on redox equations. Thanks
