Endothermic
The heat of solution of ammonium nitrate is about -25.7 kJ/mol at 25°C. This means that when solid ammonium nitrate dissolves in water, it releases this amount of energy in the form of heat.
When ammonium nitrate is mixed with water, it dissolves in the water and causes a significant cooling effect, making the solution cold to the touch. This is an endothermic reaction, where heat is absorbed from the surroundings causing the decrease in temperature. Extreme caution should be taken as large amounts of ammonium nitrate mixed with water can lead to a highly exothermic reaction, resulting in an explosion.
When ammonium nitrate dissolves in water, it increases the solubility of the compound. This leads to the formation of a solution with different properties, such as increased conductivity and a lower freezing point compared to pure water.
When ammonium nitrate dissolves in water, it absorbs energy from the surroundings to break the bonds between its ions. This absorption of energy causes the surroundings to become cooler, leading to a decrease in temperature.
When ammonium nitrate dissolves in water, it absorbs heat from the surroundings. This process is endothermic, meaning it requires heat energy, resulting in a decrease in temperature of the mixture. The temperature drop is known as the "dissolution cooling effect."

When ammonium nitrate dissolves in water, energy is absorbed from the surroundings, causing the temperature of the solution to decrease. The endothermic process of dissolution breaks the bonds within the solid crystal lattice, allowing the ammonium nitrate molecules to mix and interact with the water molecules, leading to the formation of a homogenous solution.

To reclaim ammonium nitrate after dissolving it in water, you can evaporate the water by heating the solution, leaving behind solid ammonium nitrate. Alternatively, you can also perform a chemical reaction to precipitate ammonium nitrate out of the solution, such as adding a more soluble salt to the solution to form insoluble ammonium nitrate.
When you mix distilled water and ammonium nitrate, the ammonium nitrate dissolves in the water, leading to an endothermic reaction that can cause the mixture to become cold. This solution is commonly used as a cold pack to create a cooling effect. However, it is important to handle ammonium nitrate with caution as it can be hazardous if not used properly.
Evaporating slowly thee water ammonium nitrate is obtained.
The temperature of the solution decreases
To prepare a sample of pure dry ammonium nitrate, dissolve ammonium nitrate in water to form a saturated solution, then allow the solution to cool and crystallize. Filter and dry the resulting crystals to obtain pure dry ammonium nitrate.
