Reaction between Barium chloride and Sodium sulphate
When aqueous solutions of Barium chloride (BaCl2) and Sodium sulphate (Na2SO4) are mixed together, the sulphate ions and chloride ions are exchanged between the metals forming Barium sulphate (BaSO4) and Sodium chloride (NaCl). The chemical equation for the reaction is:
(Barium (Sodium (Barium (Sodium
chloride) sulphate) sulphate) chloride)
Barium sulphate forms an insoluble precipitate and Sodium chloride remains in the solution.
(a) Displacement reactions involve displacement of a metal with lower reactivity by a metal with higher reactivity from its salt solution. In this reaction, both the metals are displaced from its salt solution. Therefore, This is not a displacement reaction.
(b) Precipitation reactions involve the formation of a solid insoluble product from the reaction of aqueous solutions of two compounds. Here, Barium sulphate is a solid formed in the reaction of two aqueous solutions. Therefore, this reaction is an example for precipitation reaction.
(c) Combination reactions involve the formation of a single larger product from more than one reactant of smaller size. Here, more than one product is formed. Therefore, this reaction is not a combination reaction.
(d) Exchange of ions between two compounds resulting in the displacement of both the metals from its solution is called a double displacement reaction. Here, sulphate ions and nitrate ions are exchanged between the metals. Therefore, it is a double displacement reaction.
Therefore, the given reaction is a double displacement reaction as well as a precipitation reaction.
