Self-Test 14.13A

Postby Sue_Park_2D » Sun Feb 05, 2017 4:44 pm

I was reading through the textbook and tried to solve out self test 14.13A on page 593.
It says: "Predict the products resulting from the electrolysis of 1 m AgNO3(aq)."
The answer is given to be [Cathode, Ag; anode, O2].

Even after reading the text and previous examples in the section, I don't understand how to determine the answer to this problem.
All I know is that I should look at the half reactions of Ag+ + e- --> Ag and NO3 -+ 2H+ + e- --> NO2 + H2O, but I don't what to do next.

Thank you in advance!

You should be looking at the half reaction of in addition to the two that you listed for . You will see that will have the lowest potential, and that will have the highest potential, higher than
