How many grams of anhydrous sodium sulphate should be used to prepare Sodium sulphate solution 60ml where Each ml contains 0.1mmol of Na plus?
To calculate the mass of anhydrous sodium sulfate needed, you first need to determine the total moles of Na+ required. In this case, 60 ml * 0.1 mmol/ml = 6 mmol of Na+. Anhydrous sodium sulfate has a molecular weight of 142.04 g/mol, so you will need 6 mmol * 142.04 g/mol = 852.24 mg or 0.85224 grams of anhydrous sodium sulfate to prepare the 60ml solution.
What is anhydrous copper sulphate?
The difference is that anhydrous copper(II) sulfate has no water of crystallisation. The anhydrous variant is a white solid while the hydrated variant is blue. Also, the chemical formula for hydrated copper(II) sulfate (or copper sulfate pentahydrate) is CuSO4.5H2O while that of the anhydrous one is CuSO4.
Why is it necessary to add anhydrous magnesium sulphate to the alcohol and ether during the sodium test?
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.
What is the difference between anhydrous sodium thiosulphate and sodium thiosulphate?
None. Anhydrous simply means ..... (not in solution). The opposite is aqueous (in solution).Added:..... crystalised without hydrate in the solid crystals.mono-hydrate means it is crystallised with 1 (one) molecule H2O per molecule salt.CuSO4.5H2O means : penta-hydrate of copper sulfate
What is the purpose of using anhydrous magnesum sulphate in the experiment?
Anhydrous magnesium sulfate is used in experiments to remove water from organic solvents. It is a desiccant that absorbs any water present in the solvent, creating a dry environment which is important for certain chemical reactions and analyses that are sensitive to moisture.
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.
Why is anhydrous sodium sulfate used in organic chemistry labs?
Anhydrous sodium sulfate is used in organic chemistry labs to remove water from organic solvents. Water can interfere with reactions or cause unwanted side products, so by using anhydrous sodium sulfate, the solvent can be dried before use to ensure the reaction proceeds as intended.

When calculating the number of moles of solid Na2SO4 the factor used is?
The molar mass of anhydrous sodium sulfate is 142,04.
What purpose does a 1 cm layer of anhydrous sodium sulfate in the apex of the funnel serve while transferring the dichloromethane extract into the round-bottom flask?
Anhydrous sodium sulfate is used as a drying agent to remove microscopic amounts of dissolved water in a solvent. It works by chemically reacting with the water by forming its hydrate, which is insoluble preferably in the solvent in this case dichloromethane. This allows one to filter off the crystals containing the water that would otherwise have remained dissolved in the dcm.

Why cap container of anhydrous sodium phosphate?
Caps contains Anhydrous sodium phosphate because this makes the plastic hard. This is used to seal bottles.
How is a unit of anhydrous?
A unit of anhydrous refers to a quantity of a substance that does not contain water, typically expressed in grams or moles. In chemistry, "anhydrous" indicates that the material has been dehydrated or is in a dry state, often important for accurate measurements in reactions or formulations. For example, anhydrous sodium sulfate (Na2SO4) is used to remove water from organic solutions. Understanding the anhydrous form is crucial for precise stoichiometric calculations in various applications.

What is the difference between sodium laureth sulfate and sodium lauryl sulfate?
Sodium laureth sulfate and sodium lauryl sulfate are both surfactants commonly used in personal care products. The main difference between them is in their chemical structure. Sodium lauryl sulfate is a harsher surfactant that can be more irritating to the skin, while sodium laureth sulfate is milder and less likely to cause irritation.
