  • Note
  1. By the end of the day, the 30% peroxide that I had taken out of the fridge was showing bubbles. Concentration of peroxide should still be greater than that of OPD.
  2. Both the Mb in isobutanol and the KCl in isobutanol gave reddish solutions of roughly the same intensity at the end of the reaction. I will have to revisit these. Perhaps I'll do that tomorrow.
