Homework Answers
- When we mix up BaCl2 and Na2SO4 we get white precipitate of BaSO4 ,and it does not dissolve in HCl.
- The test tube become white due to precipitation of barium sulphates.
- In this reaction NaCl and BaSO4 are formed ,NaCl remains dissolved in the aqueous solution, where as Barium sulphate being insoluble in water forms precipitate.
- Chemical formula of the insoluble product is BaSO4
- 2) BaCl2 + Na2SO4 -> BaSO4 + 2NaCl
- Reaction type :- It is a double displacement reaction .Sulphate ions are displaced by chloride ions and vice versa.
