Title: Curiosity
Post by: Bjc51192 on February 21, 2011, 07:54:55 PM

Hey guys im just curious, I was doing this experiment in lab, and in the experiment we mixed MnO2 , and KClO3 into a beaker. We heated the beaker, and the solution turned purple. Why did it turn purple? this has been on my mind for the past 2 days -_-

Purple usually means permanganate (MnO₄^-) solution. MnO₂ was oxidized by potassium chlorate, a pretty standard redox reaction.
