Question

what is observed when a solution of sodium sulphate added to solution of barium chloride and name the type of reaction

Answer 1

precipitation is formed

double decomposition reaction

bacl2+na2so4 =  baso4 + nacl

Answer 2

Observation of reaction between the solution of sodium sulfate and barium chloride

• When a solution of sodium sulfate is added to the solution of barium chloride, it leads to the formation of substance which is white and is insoluble in water.
• The substance which is characterized by white color and insolubility in water is called a precipitate.
• Any reaction in which precipitate is formed, it is called a precipitate reaction.
• In the given reaction, the cause of white precipitate is due to the formation of the product called barium sulfate.
• The equation involved is as follows:

$Na_2SO_4+BaCl_2\rightarrow BaSO_4+2NaCl$

• As the product $BaSO_4$ is formed through exchange of ions, this reaction is also called double displacement reaction.
