Why is it necessary to add anhydrous magnesium sulphate to the alcohol and ether during the sodium test?
Wiki User
∙ 10y ago
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]

Anhydrous magnesium sulfate is added to remove any traces of water from the alcohol and ether, ensuring a dry environment for the sodium test. Water can react with sodium and interfere with the test results, so removing it helps to ensure an accurate and reliable test.

Is anhydrous isopropanol the same thing as isopropanol?
Yes, both isopropanol and anhydrous isopropanol are forms of rubbing alcohol.
What happens if you mix alcohol and magnesium?
If mixed, Ethanol and Magnesium will react and form Hydrogen gas and Magnesium Ethoxide. 2 CH3CH2OH(liq) + Mg(s) -> (CH3CH2O)2Mg(s) + H2(g)
Preparation of C5H11OH with grignard reagent?
To prepare C5H11OH using a Grignard reagent, you would typically start with an alkyl halide such as 1-bromopentane (C5H11Br) and react it with magnesium to form the Grignard reagent, in this case, a pentylmagnesium bromide. You would then add this Grignard reagent to a carbonyl compound like formaldehyde (HCHO) or acetone (CH3COCH3) to form the desired alcohol product through nucleophilic addition. Work under anhydrous conditions and ensure proper workup including quenching the reaction with a suitable reagent.
How acetone is converted into t-butyl alcohol?
Acetone can be converted to t-butyl alcohol using a Grignard reaction. First, react acetone with magnesium metal to form a Grignard reagent. Then, the Grignard reagent reacts with isobutylene (2-methylpropene) to yield t-butyl alcohol. This process involves multiple steps and careful control of reaction conditions to ensure a successful conversion.
Why thionyl chloride is used instead of phosphorus pentachloride in chlorination of alcohol?
Thionyl chloride is preferred over phosphorus pentachloride for chlorination of alcohols because it doesn't require anhydrous conditions and can also serve as a dehydrating agent, converting the alcohol to an alkyl chloride in one step. Additionally, thionyl chloride is easier to handle and less hazardous compared to phosphorus pentachloride.
Is anhydrous isopropanol the same thing as isopropanol?
Yes, both isopropanol and anhydrous isopropanol are forms of rubbing alcohol.
How do you ensure that the final alcohol bath is free of water?
To ensure the final alcohol bath is free of water, one can use azeotropic distillation or molecular sieves to remove any remaining water molecules from the alcohol. Azeotropic distillation involves a method that uses a co-solvent to form an azeotrope that can be distilled to separate the water from the alcohol. Molecular sieves can selectively adsorb water molecules from the alcohol, leaving behind a water-free final product.
What alcohol drink contains the least amount of sulphate If you have to avoid sulphate what alcoholic drink could i order at a pub?
vodka
Why alcohol used in the limit test for sulphate?
Alcohol helps to prevent super saturation.
Why is barium chloride and alcohol used in the limit test for sulphates?
barium chloride reacts with a sulphate to produce barium sulphate which can be seen as a white precipitate and therefor identified.
Does rubbing alcohol absorb water?
Yes, alcohol does absorb water from the air, it's very hygroscopic - anhydrous copper suphate (for example) may be used to remove water from it.
Is talcum powder a solute?
Synthetic magnesium silicates are insoluble in water or alcohol.
What happens if you mix alcohol and magnesium?
If mixed, Ethanol and Magnesium will react and form Hydrogen gas and Magnesium Ethoxide. 2 CH3CH2OH(liq) + Mg(s) -> (CH3CH2O)2Mg(s) + H2(g)
What is acetylenic alcohol?
This is when acetylene reacted with one of the magnesium bromide. For instance, acteylene reacted with methyl magnesium bromide forming 3-hexa-1-eyne.
What percent of alcohol do the human body needs?
You don't need alcohol at all. It's not necessary.
Why you use alcohol in preparation of tetraamine copper sulphate monohydrate?
we use alcohol in its preparation to decrease solubility of ammonia in water so that it will react with copper to form complex and decrease solubility of complex will crystallize it out.
Can you drink wine a day after drinking citrate magnesium?
I know that when I take Magnesium Citrate, I can't get out of the bathroom long enough to go mix myself a drink. But, all joking aside, since Magnesium Citrate essentially cleans out your intestines, it would be inadvisable to drink alcohol, because you won't have any food on your stomach to buffer the alcohol.
