Ammonium chloride, #NH_4Cl#, will dissolve in water to produce ammonium cations, #NH_4^(+)#, and chloride anions, #Cl^(-)#.

Since it's a very soluble salt, it will dissociate completely according to the following chemical equation

#NH_4Cl_((s)) -> NH_(4(aq))^(+) + Cl_((aq))^(-)#

This is actually an endothermic reaction, which impliesr that heat is being absorbed from the surroundings.
