    DISSOLUTION OF AMMONIUM CHLORIDE IN WATER IS EXOTHERMIC OR ENDOTHERMIC

    Dissolution of ammonium chloride in water is exothermic or endothermic according to the following mass and enthalpy balances: Exothermic: -253.8 kJ/mol (-369.2 kcal/mol) Endothermic: +700.0 kJ/mol (+1419.5 kcal/mol)

    Dissolution of Ammonium Chloride in Water

    Dissolution of ammonium chloride in water is exothermic or endothermic.

    The exothermic process occurs when heat is released from the system, while the endothermic process consumes heat to happen. In practical terms, this means that the dissolution of ammonium chloride in water will be faster at a higher temperature.

    General Chemistry

    The dissociation of ammonia chloride in water is exothermic or endothermic, according to the amount of heat released. The temperature at which this happens is called the dissociation temperature. Ammonia chloride dissociates into nitrogen and hydrogen gas at a temperature of -35 degrees Celsius.

    Mechanism of Dissolution of Ammonium Chloride in Water

    The dissociation of ammonium chloride into hydrogen chloride and ammonium ions in water is an exothermic process, resulting in the release of heat. The endothermic process of adiabatic substitution results in the formation of a bicarbonate ion and water molecule, which lowers the pH of the solution.

    Results and Discussion

    Ammonium chlorideís dissolution in water is exothermic or endothermic depending on the temperature. At room temperature, ammonium chloride dissolves to give off heat and water vapor. The entropy of the system (the amount of disorder) is increased. At higher temperatures, more of the ammonium chloride gas will dissolve and form a liquid solution. Since the entropy is decreased in this process, it is endothermic.

    Conclusion

    The dissociation of ammonium chloride in water is exothermic with the release of heat. This suggests that the dissolution of ammonium chloride in water requires energy, which can be derived from either chemical or thermal sources. The endothermic dissociation of ammonium chloride in water may result from the transfer of heat from the surrounding environment or from within the substance itself.
