Answer:
Yes, a precipitate will form when solutions of potassium sulfate (K2SO4) and barium nitrate (Ba(NO3)2) are combined. When these two solutions are mixed, a double displacement reaction occurs, which results in the formation of solid barium sulfate (BaSO4) and aqueous potassium nitrate (KNO3).
The balanced chemical equation for the reaction is:
Ba(NO3)2 + K2SO4 -> BaSO4 + 2KNO3
In this reaction, the barium cations (Ba2+) and sulfate anions (SO42-) combine to form insoluble barium sulfate (BaSO4), which precipitates out of the solution as a white solid. The potassium cations (K+) and nitrate anions (NO3-) remain in solution as aqueous potassium nitrate.
Step-by-step explanation:
It is worth noting that barium sulfate is a highly insoluble compound, which makes it an excellent candidate for use in diagnostic imaging tests, such as barium sulfate X-ray tests, because it does not dissolve in water or organic solvents.
PRECIPITATE
The precipitate that forms is solid barium sulfate (BaSO4), which is insoluble in water and appears as a white solid.
