If 13.0g of MgSO47H2O is thoroughly heated what mass of anhydrous magnesium sulfate will remain?
8.79 grams of magnesium sulfate will remain.
How do you estimate anhydrous magnesium sulfate is enough to use?
You must state the purpose of using MgSO4.
How do you estimate the anhydrous magnesium sulphate added is enough for the solvent in the extraction experiment?
To estimate if the anhydrous magnesium sulfate added is sufficient for the solvent in an extraction experiment, you can visually assess the clarity of the solution. If the solution remains cloudy or turbid after adding magnesium sulfate, it indicates that more drying agent is needed to absorb residual moisture. Additionally, you can monitor the drying process by checking for any visible sediment of magnesium sulfate at the bottom, which suggests it's absorbing moisture effectively. Finally, ensuring that the amount added corresponds to the solvent volume and the expected moisture content can also guide your estimation.
How could a solution of magnesium sulfate and water be separated into its starting substances?
The solution of magnesium sulfate and water can be separated by a process called evaporation. The solution is heated until the water evaporates, leaving behind the solid magnesium sulfate. The remaining magnesium sulfate crystals can then be collected and the water can be condensed back into a liquid form through condensation.
Why does copper sulfate solution turn clear and magnesium develop a copper coating?
Redox! The magnesium is reducing the copper while the copper is oxidizing the magnesium. In other words, magnesium is giving electrons to the copper to bring the copper back to its metallic form while the magnesium is leaving the metal to be part of the solution as magnesium sulfate, which is colorless.
Why is anhydrous magnesium sulfate not a good drying agent to dry an ether solution of aniline?
Anhydrous magnesium sulfate is not effective for drying ether solutions of amines like aniline because it can react with the amine, forming a complex or salt that is difficult to remove. This can lead to impurities in the final product. Alternatively, a drying agent like sodium sulfate, which is non-reactive with amines, would be more suitable for this purpose.
If 13.0g of MgSO47H2O is thoroughly heated what mass of anhydrous magnesium sulfate will remain?
8.79 grams of magnesium sulfate will remain.
What is the color of magnesium sulphate?
The anhydrous magnesium sulfate is white, the heptahydrated salt is pink.
Can Magnesium Sulfate be made anhydrous by heating it to drive out the moisture?
Yes.
How many moles are present in 480g of anhydrous magnesium sulfate?
First we calculate the formula mass of the compound magnesium sulfate.Formula mass of MgSO4 = 24.3 + 32.1 + 4(16.0) = 120.4 Amount of MgSO4 in a 480g pure sample = 480/120.4 = 3.99mol There is approximately 4 moles of the compound present in a 480g sample.
What is the boiling point of magnesium sulfate in degrees Celsius?
Magnesium sulfate does not have a single boiling point as it decomposes before reaching a boiling point. Magnesium sulfate heptahydrate decomposes around 150°C, releasing water molecules and turning into anhydrous magnesium sulfate.
Would Epsom salt table salt or baking soda make the better desiccant and why?
The answer is Epsom salt. It is extremely hygroscopic when converted from the Heptahydrate form to the Anhydrous form and is an excellent desiccant. Instructions for making Anhydrous Magnesium Sulfate from Magnesium Sulfate Heptahydrate (Epsom Salts) are as follows - MgSO4 • 7H2O ==>> MgSO4 Epsom Salts is easily converted to Anhydrous Magnesium Sulfate by heating in an oven at temperatures between 200°C and 250°C . 150°C - Magnesium Sulfate Heptahydrate is converted to Magnesium Sulfate Monohydrate. 200°C - Magnesium Sulfate Monohydrate is converted to Anhydrous Magnesium Sulfate. 250°C - Complete dehydration of Epsom salts occurs yielding the desired Anhydrous Magnesium Sulfate to be used as a desiccant. 1124°C - Sublimates to MgO, SO2, SO3 before MP (Melting Point). MgSO4.7H2O = 246.4564 molecular weight MgSO4 anhydrous = 120.36 molecular weight 120..36 / 246.45 = 48.83% 246.45 / 120.36 = 204.76% Anhydrous MgSO4 absorbs 204.7% it's weight in water. As a comparison, Silica Gel absorbs 160%.
How can one determine if acetone is anhydrous?
One can determine if acetone is anhydrous by using a drying agent like magnesium sulfate or sodium sulfate. These drying agents will absorb any water present in the acetone, indicating if it is anhydrous or not.
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.

How does adding anhydrous sodium sulfate to the dichloromethane solution remove water?
Anhydrous sodium sulfate is a desiccant, meaning it has a strong affinity for water. When added to a dichloromethane solution, the anhydrous sodium sulfate will absorb any water present, effectively removing it from the solution by forming a hydrated salt. The water-free dichloromethane can then be decanted or filtered off for further use.
