Question

Name the product obtained and type of reaction given below: Na2SO4 + BaCl2 _________ + ________

Answer 1

On reaction of sodiun sulphate and bariun chloride, the products we get are
BaSo4 + NaCl2

Answer 2

Answer: Barium sulfate and Sodium chloride,

precipitation reaction

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The double displacement in which one of the product formed is a solid is called as precipitation reaction.

sodium sulphate + barium chloride :  

$Na_SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+2NaCl(aq)$
