In the following reaction, which substance is the precipitate?(NH4)2SO4(aq) + Ba(NO3)2(aq) BaSO4(s) + 2NH4NO3(aq

1) (NH4)2SO4
2) Ba(NO3)2
3) BaSO4
4) NH4NO3

The precipitate is the barium sulfate, or 3) BaSO4. This is because it is a solid (as seen by the (s)), unlike the other aqueous product. The fact that it is a solid means that it is insoluble in water and therefore a precipitate.

Hope this helps!

Answer: Option (3) is the correct answer.

Explanation:

A precipitate is defined as an insoluble solid formed when two aqueous solutions chemically combine to each other.

For example, [tex](NH_{4})_{2}SO_{4}(aq) + Ba(NO_{3})_{2}(aq) \rightarrow BaSO_{4}(s) + 2NH_{4}NO_{3}(aq)[/tex]

Since, it is known that (aq) represents aqueous and (s) represents solid. So, in this reaction barium sulphate ([tex]BaSO_{4}[/tex]) is the insoluble solid.

Hence, [tex]BaSO_{4}[/tex] is the precipitate that is formed.

Thus, we can conclude that in the given reaction [tex]BaSO_{4}[/tex] substance is the precipitate.
