Because of its affinity for water, anhydrous sodium sulfate is often used to dry hydrophobic solvents used in aqueous organic extractions. For example a water based sample is extracted for organic compounds using dichloromethane, or ethyl ether in a separatory funnel. The organic layer is passed through a buchner funnel holding anhydrous sodium sulfate, yielding dried solvent extract.
The purpose of anhydrous sodium sulfate is an absorption of a wet organic. It causes water to separate fully from the solvent.
hydrated form has 10 water molecules, i.e Na2SO4.10H2O
it is also known as Glauber's salt
Anhydrous sodium sulfate is considered as a drying agent. It is used in expirements to remove water from a solution or during an expirement.
hope this helps.
Many chemical procedures needs dried reagents.
To dry the organic layer
To get rid of excess water in the organic phase.
If you mean what percentage of sodium sulfate is Na, the answer is about 32.4. That's for the anhydrous material. It can also be hydrated. In Glauber's salt, for example, a molecule of Na2SO4 is associated with 10 molecules of water. %Na = 14.3.
Aluminium Sulphate is Al2(SO4)3 and its mass is27x2 + 96x3 = 342g/mole
Sodium sulfate, in its anhydrous form (meaning without water) is a white crystalline salt. Wikipedia has more information, and a link is provided.
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.
