Drying with magnesium sulfate leaves very tiny residues in your flask which need to be filtered off as decanting won't get rid of them. Leaving these tiny residues in the flask while running a distillation can cause the solvent to "bump"; in other words to violently erupt and run into your condenser, thus rendering your distillation ineffective.
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.
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.
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.
The formula of anhydrous copper sulfate is CuSO4.
Anhydrous copper sulfate is CuSO4, while water is H2O. When anhydrous copper sulfate reacts with water, it forms hydrated copper sulfate, which is CuSO4·5H2O.
8.79 grams of magnesium sulfate will remain.
The anhydrous magnesium sulfate is white, the heptahydrated salt is pink.
Yes.
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.
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.
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%.

You must state the purpose of using MgSO4.
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.
Anhydrous (dehydrated) Epsom salt is magnesium sulfate, MgSO4. The formula for the hydrate is MgSO4 (4H2O)
The formula of anhydrous copper sulfate is CuSO4.
Anhydrous copper sulfate is CuSO4, while water is H2O. When anhydrous copper sulfate reacts with water, it forms hydrated copper sulfate, which is CuSO4·5H2O.
