Question

A reaction between barium hydroxide and ammonium chloride results in no precipitate, but how will we find that a reaction occurred.

Answer 1

Answer:

Ammonium chloride has ammonium (NH4 +) part which is slightly acidic and Barium Hydroxide is a strong base.

You can see that an acid-base reaction will occur.

In this case :

Its highly endothermic reaction

Forms aqueous ammonia (mind that ammonia is highly water soluble gas so no effervesence) and Barium Chloride which is water soluble.

Ba(OH)2 +NH4Cl ——->BaCl2 + NH3 +H2O (unbalanced)

Answer 2

hii.

please follow me and brain list answer

Ammonium chloride reacts with barium hydroxide to form ammonia. ... Reaction between (barium hydroxide) Ba(OH)2 + NHCI (ammonium chloride) is a double displacement gas evolution reaction. The products of this reaction are Barium Chloride (BaCI2), Ammonia (NH3) and Water (H2O
