Two graduate students were injured today (Wed., 2/9/2000) when an explosion occurred when they were mixing two acids.

The students at the Massachusetts Institute of Technology (MIT) were mixing nitric and hydrochloric acids in a glass container at the Memorial Drive building this afternoon when the chemicals exploded.

University spokesman Bob Sales said the process was done regularly "and they should not explode when mixed."

Safety officials are investigating the possibility that another chemical may have been in the container.

The students --- a man and a woman --- were treated for minor injuries at the Mass. General Hospital and later released.
