Add some barium chloride solution to the neutral or weakly acid sulfate solution
The water solution of magnesium sulfate is not acidic.
This compound is an ironIII) penta aqua nitrosyl sulfate.
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.
Hayem's solution. This is an isotonic fluid which consists of the folIowing constituents (in g/100 ml):sodium chloride 0.5, sodium sulphate 2.5 and mercuric chloride 0.25. The sodium sulphate discourages clumping of the erythrocytes and the mercuric chloride is a preservative.
The precipitate will be barium sulfate. The reaction is as follows:BaCl2(aq) + Na2SO4(aq) ==> 2NaCl(aq) + Ba(SO4)(s)
IronIII sulfate dihydrate written in chemical form is Fe2(SO4)3.2H2O
Since barium chloride is reactive with sulfate ions there would be more precipitate present. The solution with more precipitate present would show it had higher amounts of sulfate ions
7.00 g baso4
Fe2(SO4)3
calcium sulfate
The white solid precipitated when an aqueous solution of barium chloride is mixed with an aqueous solution of sodium sulfate is named "barium sulfate" and has the formula BsSO4.
add water to dissolve the sodium chloride, filter and you can collect the barium sulfate behind the filter paper
No reaction occurs
precipitate of balium sulphate and solution of sodium chloride is formed!
Add some barium chloride solution to the neutral or weakly acid sulfate solution
Na2SO4 +CaCl2---------------> 2NaCL +CaSo4
