  • What Happens When You Add Ammonium Nitrate to Water ...

    While some heat is produced when the ammonium nitrate ions interact with the water molecules (i.e., an exothermic reaction), it is a lot less than what is needed for the water molecules to disperse the strong ionic bonds of the ammonium nitrate, so the overall process is an endothermic reaction, or one that absorbs energy from its surroundings.
