<p>So I'm just finishing up redox reactions. I still don't understand one thing though. How does an acidic or basic environment affect the products formed by the redox reactions? For example, MnO4- has like 4 diff states, and Mn2+ happens to dominate if permanganate is in an acidic solution, whereas if it's in either a neutral or basic solution, MnO2 does.</p>

<p>I need an answer ASAP because I have a test today. This part is the only principle i'm not sure about.</p>

<p>This response is likely much too late, but oh well.</p>

<p>My AP Chem teacher, who is fantastic by the way, didn’t really mention a ‘why’ for Permanganate’s reactions in an acidic versus a basic solution; I think it’s just one of those things that needs to be memorized. There are not many other commonly used ions that work like Mn in it, however, so you should be fine with just branding that tidbit into your brain.</p>
