Hello!  I'm a grad student at a university working in a safety office.  One of the research labs on campus performed the following reaction:
700 ml concentrated 98% H2SO4
500ml 70% HNO3
40gm graphite
480 gm KCLO3

in a 2 L erlenmeyer flask.

Gas is being created as well as a white pellet on the bottom.  We're trying to figure out if this is dangerous, explosive or what.  Any info would be greatly appreciated.  Again, I'm just a student trying to get more info on this, there are other more qualified people dealing with this, I'm just trying to help.

Thanks!

Hmm.. that dosent seem weary smart:

First concentrated Sulfuric acid and KClO3 makes HClO3, which is an explosive gas.
HClO3 reacts readyly with organic stuff, (like carbon), and makes some funney results.. With the Concentrated nitric acid, i have no idea what happens, best to secure the solution and ship it out of the house
