Ammonium nitrate (NH4NO3) dissolves readily in water

Last updated: 8/2/2022

Ammonium nitrate (NH4NO3) dissolves readily in water eventhough the dissolution is endothermic by 26.4kj/mol. The solution process is spontaneous because 1. of the increase in enthalpy upon dissolution of this strong electrolyte 2. the vapor pressure of the water decreases upon addition of the solute 3. of the increase in disorder upon dissolution of this strong electrolyte 4. osmotic properties predict this behavior 5. of the decrease in enthalpy upon addition of the solute
