SO42-
It is not mandatory to heat this solution.
sodium carbonate and barium chloride react to form sodium chloride and barium carbonate Na2CO3 +BaCl2 -------> 2NaCl +BaCO3
For example sodium tetradecyl sulfate.
Potassium and nitrate don't react, stay unchanged as hydrated ions in solution, called spectator ions. Only sulfate and barium ions react by precipitating to solid. (SO42-)aq + (Ba2+)aq --> (BaSO4)s :)
Sodium sulfate solution is neutral; the red litmus is purple.
add water to dissolve the sodium chloride, filter and you can collect the barium sulfate behind the filter paper
If the sodium sulfate and barium nitrate are both in solution in water, a precipitate of barium sulfate will be formed, because this salt is much less soluble in water than barium nitrate, sodium sulfate, or sodium nitrate.
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.
Sodium sulfate is highly soluble in water, but insoluble in most organic solvents. If you want to increase its solubility in water (as for any salt), you can heat the solution or remove one of the products (sodium ions or sulfate ions) from solution. I can't think of any insoluble sodium salts, but barium sulfate (BaSO4) is insoluble in water. Thus, adding barium chloride (or some other soluble barium salt) will remove sulfate from the equilibrium (due to BaSO4 precipitation) and increase the solubility of sodium sulfate.
precipitate of balium sulphate and solution of sodium chloride is formed!
1. Put the mixture of powders in a beaker and add water. 2. Stir vigorously. Sodium chloride is dissolved, barium sulfate not. 3. Filter to separate sodium chloride solution (passes the filter) from barium sulfate as a solid on the filter.
If both of the compounds named in the question are in solution in water, barium sulfate will precipitate. If both are solids when mixed, there will usually be no reaction.
Barium chloride can be precipitated wit a sulfate; barium sulfate is then filtrated.
Barium Sulphate
By filtration barium sulfate being insoluble in water.
The precipitate will be barium sulfate. The reaction is as follows:BaCl2(aq) + Na2SO4(aq) ==> 2NaCl(aq) + Ba(SO4)(s)
Barium Chloride + Sodium Sulfate --> Barium Sulfate + Sodium Chloride BaCl2 + Na2So4 --> BaSO4 + 2NaCl It's called a Double Displacement reaction because Barium(Ba2+) and Sodium(Na+) displaces each other from their original anions. It's also called a Precipitation reaction because a white precipitate is formed after the reaction due to Barium Sulfate(BaSO4) as it is insoluble.
