<p>Hey,
I'm studying for my SAT II Chem on June and I've been through everything in the Barron's book except oxidation-reduction and electrochemistry. I'm not in AP so i haven't learned this topic and my teacher, who's currently helping me crash-course everything says it's a way too lengthy topic. How much of the oxidation-reduction/electrochemistry do i need to know like what are the main points?</p>
<p>thanks alot :)</p>
<p>There were at least 2 questions on the May test that dealt with oxidation-reduction.</p>
<p>One asked you to recognize an oxidation-reduction reaction…you should be able to assign oxidation states and to recognize oxidation-reduction reactions (usually it’s two metals in a double replacement reaction).</p>
<p>Be familiar with the oxidation states common elements take (the prep book should cover this). The other oxidation-reduction question asked you to assign the oxidation state of an element before and after the reaction.</p>
<p>As for electrochemistry, I don’t remember seeing it in June.You should probably understand the basics of it - how it works, what happens at the anode and cathode, what happens to the concentrations as the battery runs, and what electrolysis is (basically the reverse of a spontaneous battery reaction).</p>
<p>There won’t be anything too complex, but have the basics down. It might save you points. (Edit) It might be a good idea to skim through the Princeton Review chapters on this. The PR book is much more compact and basic than Barrons, which might be want you want.</p>
