a drying agent works by removing water molecules that may be contaminating a chemical product. Magnesium Sulfate (MgSO4) is an ionic salt. The charged Mg2+ and SO42- ions have a high affinity for water molecules and therefore are able to remove them from the product thus "drying it" of water. In this sense "drying" means "removing water" rather than "making less wet"

Why is it necessary to add anhydrous magnesium sulphate to the alcohol and ether during the sodium test?
Anhydrous magnesium sulfate is a drying agent which removes water molecules which might cause contamination to the product. The high attraction for water molecules was due to the charged Mg2+ and SO42- ions. [2]
If i mix Magnesium oxide and sulphuric acid?
You can react sulphuric acid with magnesium oxide.The reaction will look a little like this. sulphuric acid + magnesium oxide -> magnesium sulphate + water. However the salt dissolves into the liquid so u get a solution, a nd if u add universal indicator it will turn darkish blue for it is a alkaline.
Why is anhydrous magnesium sulfate not a good drying agent to dry an ether solution of aniline?
It exists as stable crystals therefore packing fraction is very low and it can not accept the water molecules.
Why it is necessary to filter off the anhydrous magnesium sulfate before distillation?
Drying with magnesium sulfate leaves very tiny residues in your flask which need to be filtered off as decanting won't get rid of them. Leaving these tiny residues in the flask while running a distillation can cause the solvent to "bump"; in other words to violently erupt and run into your condenser, thus rendering your distillation ineffective.
How can you tell if a hydrate has turned into an anhydrous salt?
1- on heating the mass of material becomes reduced due to elimination of water molecules. 2- in some cases the colour change may be observed as penta hydrated copper sulphate is blue while anhydrous copper sulphate is a white solid.

What is magnesium sulfur used in?
Magnesium Sulphate Powder, comprising of magnesium, sulphur and oxygen, is considered as vital for plants growth and to replenish the deficiency of magnesium or sulfur in the soil. These are widely sprayed or applied on roses, potatoes, lemon trees, tomatoes, peppers and carrots. With its high solubility in water, the magnesium sulphate powder is best for foliar feeding applications.Its applications include:» Polishing Abrasives for Marble, granite, tiles, vitrified tiles, and other country (local) stones» In Agriculture as a secondary nutrient» In process industry as a catalyst» Dietary Supplement and Laxative in Animal health & feed» Detergent Industries» Refractories» Textile Industry» Ceramic Industry» Weighing of silk» Mineral water» Fire proof material

What is the role of anhydrous sulfate?
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.
Is sodium C14-16 olefin sulfonate a sulphate?
No. it is sulfate free but I hear it can be irritating and drying as SLS but i have used it with no drying and irritation.

What can magnesium sulfate and heptahydrate be used for?
Anhydric Magnesium sulphate can be used as a drying agent for wet organic solvents or solutions of organic compounds in organic solvents. It dries faster than the commonly used anhydric calcium chloride.

1- on heating the mass of material becomes reduced due to elimination of water molecules. 2- in some cases the colour change may be observed as penta hydrated copper sulphate is blue while anhydrous copper sulphate is a white solid.
What are the uses of alkaline earth metal?
Magnesium oxide is used in the lining of furnaces. Magnesium hydroxide is used in making of anti-acid tablets. Calcium chloride is used in the extraction of sodium metal,to lower the melting point of NaCl. Calcium sulphate is used as plaster of paris to set fractured bones. Calcium oxide is used as a drying agent,is also used to raise the soil pH.
What is the empirical formula for calcium sufate?
The anhydrous form used as a drying agent is CaSO4 There are hydated forms, CaSO4 0.5H2O (plaster of paris) and CaSO4.2H2O, gypsum
Why you use anhydrous ether during the preparation of Grignard's reagent why not anhydrous hexane?
You should really use anhydrous hexane; however, ethers can absorb large quantities of water; THF is completely miscible with water and will thus require extensive drying in order to get an anhydrous environment. Hexane absorbs very little water due to the unfavourable interactions between it and water. Therefore "non-anhydrous" hexane contains such a small quantity of water that the Grignard reagent formed will more than adequately dry the hexane.
