What is the mechanism of chlorosulfonation of benzene?
2015年3月17日 · Response to Ron: For the chlorosulfonic acid mechanism, the ref your provided is a review book which links to a journal from the Russian Journal of Organic Chem from 1975. I unfortunately can only access the abstract because that year does not appear to be electronically uploaded and I don't have access to the physical copy of the journal.

Mixing hydrochloric acid and sulphuric acid, both concentrated
2018年3月27日 · In the chemistry lab, I stupidly decided to mix hydrochloric acid and sulphuric acid, both concentrated, in a random ratio, which was about $\pu{50 ml}$. When I poured them in one test tube, the result was a vigorous reaction, with the green coloured liquid mixture "jumping" in the test tube and a white gas being released.
