Determine the reaction between ammonium sulfide and barium bromide and analyze if it will produce a precipitate or not
Ammonium sulfide is composed of ammonium (polyatomic cation → NH4+) and sulfide (polyatomic anion → S2-). Molecular formula will appear as (NH4)2S. Recall that for ionic compounds, the charge of the ion goes to the subscript of the counterion
Separate solutions of ammonium sulfide and barium bromide are added to the same flask. Which of the following most accurately describes the reaction?
I. Barium sulfide precipitates out of solution.
II. Barium ions remain as spectator ions.
III. Ammonium bromide precipitates out of solution.
IV. Ammonium ions remain as spectator ions.
A. I and IV
B. II and III
C. I only
D. II only
E. There is no reaction; all species remain as spectator ions.
