Question

Na2SO4 (aq) +BaCl2(aq) =2 NaCl (s) + BaSO4 (aq)


Is this reaction an example of precipitation reaction? Also give reason for your answer.

​

Answer 1

Answer:

Na2SO4 (aq) + BaCl2 (aq) -> BaSO4 (s) + 2NaCl (aq) . In the above reaction , a precipitate is formed of Barium sulphate and hence it is a precipitation reaction

Explanation:

BaCl

2

(aq)+Na

2

SO

(aq)→BaSO

(s)+2NaCl(aq)

The types of reactions are (b) Precipitation and (d) Double displacement.

A precipitate of bariumsulphate is obtained.

In double displacement reaction, two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
