Answer : BaS[tex] O_{4} [/tex] will be the precipitate which will be formed.
Explanation : When all the three solutions namely; [tex]NaSO_{4} + Ba(NO_{3})_{2} + NH_{4} ClO_{4} [/tex] are mixed together a white precipitate of BaS[tex] O_{4} [/tex] is formed as a product in the solution along with the soluble by product of Ammonium nitrate which is [tex]NH_{4} NO_{3}[/tex]
The precipitate formed when solutions of Na₂SO₄, BaNO₃ and NH₄ClO₄ are mixed is BaSO₄.
Precipitates are those substances which are present in any solution in the insoluble form and will be calculated by filteration.
It is clear that aqueous solution of Na₂SO₄, BaNO₃ and NH₄ClO₄ means all of them are present in their ions forms. And when we add all these together then the formation of BaSO₄ which is insoluble in water and present in the form of white precipitate.
Hence formed precipitate is barium sulphate.
