Why is anhydrous sodium sulfate used in organic chemistry labs?
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.

Common uses for cesium?
•Cesium is used as a catalyst in the hydrogenation of certain organic compounds. •Cesium fluoride is widely used in organic chemistry as a base and as a source of anhydrous fluoride ion. •They are used in Atomic Clocks. •They are also used in the Brachytherapy treatment
What is the purpose of the saturated NaCl solution for washing an organic layer why not use deionized water?
The bulk of the water can often be removed by shaking or "washing" the organic layer with saturated aqueous sodium chloride. The salt water works to pull the water from the organic layer to the water layer. This is because the concentrated salt solution wants to become more dilute and because salts have a stronger attraction to water than to organic solvents. Note: sometimes a saturated aqueous solution of sodium chloride is called brine.
Is soil an ore?
No it is not. Soil is simply a deposit of organic material, an ore is something which contains enough of a metal to make its extraction worth while e.g FeO (Iron oxide)
Why anhydrous sodium sulfate is used in experiment?
to remove water from the organic phase after an extraction.
Why brine solution is used in organic chemistry extraction?
Remove water

How do you separate an organic compound and an inorganic?
extraction
Why is anhydrous magnesium chloride insoluble in organic solvents?
because of ionic compound.
Is anhydrous H2CO3 ionic or molecular?
This is a covalent compound.
Why dichloromethane were used as a solvent in liquid-liquid extraction?
chlorine atoms have high electronegativity, which will distort the electron cloud of the molecule. DCM is highly polar, and it is also an organic molecule. thus it is a good solvent for other organic molecules, very often used in non-biological organic synthesis.
What is Lukas's reagent?
Lucas' reagent is a solution of anhydrous zinc chloride in concentrated hydrochloric acid used to classify low molecular weights of alchohols. In 1930, this test became the standard method in qualitative organic chemistry.
Why ether is use as an extraction solvent?
For extraction of organic solvents generally diethylether is used because organic substances are generally soluble in ether and ether has got a low boiling point making its removal after the extraction very easy.
The role of sodium chloride in extraction method?
Brine (saturated sodium chloride solution) is usually the last solution used in an aqueous wash to help remove trace amounts of water (and anything water soluble) from the organic layer. Many chemists skip this step however, since sodium sulfate or manganese sulfate is used to remove water from the organic layer anyway, after the organic layer is separated.
