Dissolution is generally exothermic.
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
The process of dissolving ammonium nitrate (NH4NO3) in water is considered endothermic, meaning it absorbs heat from the surroundings. However, an example of an exothermic dissolution process is the dissolving of sodium hydroxide (NaOH) in water. When NaOH dissolves, it releases heat, resulting in an increase in temperature of the solution.
A common example of safe chemicals that produce an endothermic reaction when combined is ammonium nitrate and water. When ammonium nitrate dissolves in water, it absorbs heat from the surroundings, causing a drop in temperature. This process is often utilized in instant cold packs. Another example is the combination of baking soda and vinegar, which absorbs heat during the reaction, although it is not as pronounced as with ammonium nitrate and water.
Ammonium nitrate is a product from a fertilizer plant.

Endothermic. That is why it is used in ice packs.

The temperature of the solution decreases
The energy factor for dissolving ammonium nitrate ions in water is endothermic, meaning it requires energy input to break the ionic bonds between the ammonium and nitrate ions. As the ions dissociate in water, the hydrogen bonds between water molecules and the ions form, leading to an increased disorder in the system and requiring energy to overcome the attractive forces between the ions.
The dissolution of potassium nitrate in water is an endothermic process.
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 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.

No, not all spontaneous processes are exothermic. Spontaneous processes can be exothermic (release heat), endothermic (absorb heat), or not involve a change in heat at all. The spontaneity of a process is determined by a combination of factors such as entropy, enthalpy, and temperature.
