How would you test the presence of sulfate ions?
To identify the presence of sulfate ions in a solution, follow these steps: To acidify the sample, add a few drops of dilute hydrochloric acid (HCl) to the sample. Then, add a few drops of dilute barium chloride (BaCl2) solution to the sample. If sulfate ions are present in the solution, a white precipitate of barium sulfate (BaSO4) will form. The reaction is: Ba²⁺ (aq) + SO4²⁻ (aq) → BaSO4 (s) For example, if we have a solution of magnesium sulfate (MgSO4), the reaction would be: BaCl2 (aq) + MgSO4 (aq) → BaSO4 (s) + MgCl2 (aq) By observing the formation of the white precipitate, we can confirm the presence of sulfate ions in the sample.
What are the ions present in a solution of BaCl2?
the barium ion Ba2+ and the carbonate ion CO32+
How can you test a solution for the presence of ba ions?
Add a sulfate solution: BaSO4 precipitates!
What is the reaction of barium sulfide and water?
A strong electrolyte dissociates completely into ions in aqueous solution. When barium sulfide, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.BaS(s) Ba2+(aq) + S2-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
What mon atomic ions do barium and selenium make?
An ionic compound, Barium selenide or BaSe is formed, with the ions Ba2+ and Se2-.
How can you test a solution for the barium ions?
Acidify the given solution with a few drops of concentrated HNO3 followed by the addition of 4 mol dm-3 sulphuric acid or ammonium sulphate. A white precipitate implies that there are Barium (II) ions present in the solution. The objective of the test give above is to recognize the Barium(II) ions as the white precipitate of barium sulphate which is not soluble in most of the solvents. Adding a sulphate solution at first might cause distractions as other cations such as strontium also make white precipitates with sulphate ions. Those other precipitates dissolve in dilute nitric acid.
How many barium ions are there in 250 mL of a barium iodide solution that has an iodide ion concentration of 0.125 M?
The number of barium ions is 0,188.10e23.
How do you test for sulphate ions?
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
I woke up this morning with a solution next to my bed and assumed it was a cationic solution and added some HCl to it which didn't produce a precipitate and flame test was pale green so what is in it?
My friend, it would appear you have a solution containing barium ions. If you would like add some sulfuric acid to precipitate the barium as barium sulfate.

Why does barium nitrate in sodium hydroxide form a precipitate?
In aqueous solution, barium nitrate and sodium hydroxide undergo a double replacement reaction, in which barium ions combine with hydroxide ions to form barium hydroxide and sodium ions combine with nitrate ions to form sodium nitrate. Barium hydroxide is insoluble in water, so it precipitates out of solution. Ba(NO3)2(aq) + 2NaOH(aq) --> Ba(OH)2(s) + 2NaNO3(aq)
Is Na2SO4 soluble in water?
Yes, sodium sulfate is water soluble. Many sulfates are soluble in water. A notable exception is barium sulfate, whose insolubility forms the basis of a test for the presence of sulfate ions. Add barium chloride to a solution containing sulfate ions. The white barium sulfate precipitate is a positive test for sulfate ions.
What is the test for barium ions?
Gives white precipitate when Sulfuric acid added!
What are the ions present in a solution of BaCl2?
the barium ion Ba2+ and the carbonate ion CO32+
How many TOTAL ions (barium cations plus acetate anions) would be produced as aqueous species in the water solvent if four molecules of barium acetate dissolved?
Eight ions are in the solution.
What will be the observations when Zinc nitrate solution is added to Barium chloride solution?
The solution contain ions as: Zn2+, (NO)-3, Ba2+, Cl-. Any reaction.
