Question

When ammonium chloride dissolves in water, the solution becomes colder. (a) is the solution process exothermic or endothermic? (b) why does the solution form?

Answer 1

it is endothermic

Step-by-step explanation:

When ammonium nitrate is dissolved in water, no new products are formed. It absorbs heat from the surroundings. It is called the energy of hydration. The ∆H for this process is negative. Hence, it is an endothermic process.

Answer 2

The solution process is exothermic because when solution become colder heat energy is released which make the process exothermic. The exothermic process is the process in which heat is released.The solution forms inorder to separate NH4+ ions and Cl- ions
