However, the use of sealed tubes containing hydroiodic acid is very dangerous for the chemist, since the pressure of the free hydrogen liberated in the tube may exceed 100 atmospheres, and terrible accidents due to bursting of the tubes have been all too frequent.
A still more powerful agent belongs to this group, namely a concentrated solution of hydroiodic acid, the use of which we owe to Berthelot.
The use of these tubes also has another disadvantage, this time of a purely chemical nature; the presence of concentrated hydroiodic acid often causes isomerization of the reducible substance.
