    Interesting Exothermic Reaction

    I have a question about the reaction that occurs when roughly equal amounts of DMSO + HCl + H2O2 (~15%) are combined in a small tube. I did this, and the tube instantly became warm. I set it aside, then about 3 minutes later I heard a hissing sound. The liquid was boiling violently. It did this...

    What are each steps of the reaction? I am having a really hard time with this!

    The first step included combining chromium chloride hexahydrate and dimethylsulfoxide together and heating at 190 degrees Celsius (a gas was formed, solution turned a violet colour), and the solution was cooled to 70 degrees Celsius. Then, 0.5 mL of ethylenediamine in 1.0 mL of ethanol was...
