Final answer:
The question involves a double displacement reaction between ammonium sulfate ((NH4)2SO4) and strontium hydroxide (Sr(OH)2), which produces water (H2O), ammonia gas (NH3), and strontium sulfate (SrSO4) as a precipitate.
Step-by-step explanation:
You're dealing with a chemical reaction between ammonium sulfate and strontium hydroxide, which is a double displacement reaction. When these compounds react in aqueous solution, ammonium hydroxide and strontium sulfate are formed. However, since ammonium hydroxide is weak and partially dissociates into water and ammonia gas, the observable products are more accurately water, ammonia gas, and strontium sulfate.
The complete balanced chemical equation for this reaction would therefore be:
- (NH4)2SO4(aq) + Sr(OH)2(aq) → 2 NH4OH(aq) + SrSO4(s)
- 2 NH4OH(aq) → 2 H2O(l) + 2 NH3(g)
SrSO4 is insoluble in water and will precipitate as a solid, so you would expect to see a precipitate forming in the solution. This is a precipitation reaction and it often results in the formation of a solid compound from two aqueous reactants.
