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]
It is important to weigh an anhydrous substance with a cover on because the solid may be lost to the air during the measuring of the weight.
It is important to avoid air bubles in the column during chromatography because you get a clearer picture and will see what ishappening alot clearer without problems.
It means that you keep the temperature constant during the entire run
During the electrolysis of Copper sulphate ,at the cathode ,copper and hydrogen both being positively charged migrate towards the cathode.While at the anode
Blue vitriol is a very obsolete name for the copper(II)sulphate: CuSO4. Don't use in the future this term. Pentahydratated copper(II) sulphate: CuSO4.5H2O - bright blue color After the dehydratation of the above compound we obtain the anhydrous copper(II) sulphate: CuSO4 - pale green color.

Moblie phase is that phase in chromatography that moves the analyte components along with it. Stationary phase remains static during chromatography.
Chromatography was discovered by Ms.Felicetti & Sherlynne & Emily In 2011 during the investigation of a Science Fair Project

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.
Tin Sulphate stays the same during electrolysis because it is low down in the reactivity series, it can only be extracted by the reduction of carbon, not by electrolysis.

It refers to a set of technique used to separate different compounds. So involves separating chemicals and identifying them by color. Various chromatography products are used during the process.

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.
