What happens, when ammonium chloride is added to barium hydroxide ? What changes in temperature take place during the reaction ?

Explanation

When ammonium chloride is added to barium hydroxide, it forms barium chloride, ammonia and water.
`underset("Barium hydroxide")(Ba(OH)_(2))+underset("Ammonium chloride")(2NH_(4)Cl) to underset("Barium chloride")(BaCl_(2))+underset("Ammonium")(2NH_(3))+underset("Water")(2H_(2)O)`
During the reaction temperature is lowered since the reaction is endothermic.
