3. For the reaction between aqueous barium nitrate and aqueous sodium sulfate, producing barium sulfate (solid) and aqueous sodium nitrate:

(a) Write the equation for this reaction.
(b) Balance the equation from Part (a).
(c) Classify the reaction.



Answer :

Final answer:

The detailed answer provides the balanced chemical equation, confirms the formation of a precipitate, and classifies the reaction type.


Explanation:

(a) The balanced chemical equation for the reaction is: Ba(NO3)2(aq) + Na2SO4(aq) -> BaSO4(s) + 2NaNO3(aq).

(b) Yes, a precipitate of barium sulfate (BaSO4) forms in this reaction.

(c) This reaction is a double displacement reaction, also known as a precipitation reaction, where two ionic compounds switch ions to form two new compounds.
