Yes, it is true. The equation of reaction is :-
BaCl2 + Na2SO4 --------> 2NaCl(aq.) + BaSO4
where solution is of sodium chloride and Barium sulphate settles down at the bottom as precipitate
White precipitate of barium sulphate
Add water and pass it though a filter. Ammonium sulfate will dissolve in water, barium sulfate will not.
whencalcium chloride reacts with barium nitrate calcium nitrate and barium chloride wil be formed. whencalcium chloride reacts with barium nitrate calcium nitrate and barium chloride wil be formed.
No problems, barium sulphate is insoluble.
barium choride and calcium sulphate will form
Add the mixture in water ammonium chloride is highly soluble in water while Barium sulphate is insoluble , filter the solution the residue(solid part) is Barium sulphate, evaporate the solution and get solid Ammonium chloride.
White precipitate of barium sulphate
sodium carbonate and barium chloride react to form sodium chloride and barium carbonate Na2CO3 +BaCl2 -------> 2NaCl +BaCO3
barium chloride plus sodium sulphate yields barium sulphate plus sodium chloride
the product will be a milky solution. It is opaque.
add barium chloride or barium nitrate to a solution containing sulphate ions SO4 2-. To the same solution add hydrochloric acid in excess. OBSERVATIONS, a white precipitate which is insoluble in excess acid confirms presence of SO42- IF IT DISSOLVES then it confirms SO32- ----------------------------------------- 1) Add barium nitrate solution under acidic conditions (use an equal volume of hydrochloric acid) to the unknown solution 2) A white precipitate of barium sulphate forms if sulphate ions are present
precipitate of balium sulphate and solution of sodium chloride is formed!
Add water and pass it though a filter. Ammonium sulfate will dissolve in water, barium sulfate will not.
whencalcium chloride reacts with barium nitrate calcium nitrate and barium chloride wil be formed. whencalcium chloride reacts with barium nitrate calcium nitrate and barium chloride wil be formed.
Nothing - barium chloride is soluble. You can however precipitate either the barium (e.g. with sodium sulphate, giving barium sulpate, or the chloride, e.g. with silver nitrate giving silver chloride precipitate.
Add some barium chloride solution to the neutral or weakly acid sulfate solution
barium chloride reacts with a sulphate to produce barium sulphate which can be seen as a white precipitate and therefor identified.
