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

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
