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.
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
The formula for sodium sulfate is Na2SO4. Therefore, there are 2 sodium atoms, one sulfur atom, and 4 oxygen atoms, for a total of 7.
Balanced equation. 2NaOH + H2SO4 -> Na2SO4 + 2H2O 12.5 grams NaOH (1 mole NaOH/39.998 grams)(1 mole Na2SO4/2 mole NaOH)(142.05 grams/1 mole Na2SO4) = 22.2 grams sodium sulfate produced ===========================
The answer is approx. 2 moles (for anhydrous sodium sulfate).
Sodium is the cation (+1 charge), sulfate is the anion (-2 charge) The chemical formula tells us there are two sodium ions (Na2) and one sulfate (SO4) ion.
41,1 g of sodium sulfate (Na2SO4, anhydrous) contain 10,455.10e23 atoms.
How many grams of Na+ are contained in 25 g of sodium sulfate (Na2SO4)?
3.23

Add barium chloride to a solution containing sulfate ions. The white barium sulfate precipitate is a positive test for sulfate ions.
Since the formula shows two sodium atoms in each formula unit of sodium sulfate and this compound normally completely ionizes in water solution, the number of sodium ions will be twice the number of moles of the salt; in this instance, 1.0 moles of sodium ions.
