Which is more effective at raising the boiling point of a soup? Why? SrBr2 Ca3N2 KCl CH4
Boiling point elevation is proportional to the number of species in solution; it is a colligative property.
Calcium nitride would give by far the most particles in solution on a per mole basis, and of course, the ammonia would speciate.
The only such contaminant I would put in my soup would be
