If 13.0g of MgSO47H2O is thoroughly heated what mass of anhydrous magnesium sulfate will remain?
8.79 grams of magnesium sulfate will remain.
If 5.742g of hydrated magnesium sulfate is heated 2.801g of anhydrous magnesium sulfate remains Determine the formula of the hydrated form?
The formula of the hyrdrated from should be MgSO4 . 3H2O.
How do you estimate anhydrous magnesium sulfate is enough to use?
You must state the purpose of using MgSO4.
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?
It exists as stable crystals therefore packing fraction is very low and it can not accept the water molecules.
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.
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%.
If 5.742g of hydrated magnesium sulfate is heated 2.801g of anhydrous magnesium sulfate remains Determine the formula of the hydrated form?
The formula of the hyrdrated from should be MgSO4 . 3H2O.
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 the solution of epsom salts prepared by dissolving magnesium sulfate heptahydrate in water is added to a solution containing sodium lauryl sulfate will a precipitate form?
No. Sodium lauryl sulfate will not form insoluble salts with the magnesium.
What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
What is the formula for epson salt?
Anhydrous (dehydrated) Epsom salt is magnesium sulfate, MgSO4. The formula for the hydrate is MgSO4 (4H2O)
