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?
0.336g of anhydrous sodium sulphate
Why is it necessary to add anhydrous magnesium sulphate to the alcohol and ether during the sodium test?
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]
Is calcium sulfate bad for health?
Calcium sulfate is a common laboratory and industrial chemical. In the form of γ-anhydrite (the nearly anhydrous form), it is used as a desiccant. It is also used as a coagulant in products like tofu. In the natural state, unrefined calcium sulfate is a translucent, crystalline white rock. Generally, it is safe, however like all inert anhydrous powders, it does carry the risk of causing irritation to mucosa membranes, especially when inhaled or in the eyes.
What is na2hp04?
Monosodium phosphate (NaH2PO4), also known as anhydrous monobasic sodium phosphate and sodium dihydrogen phosphate, is a chemical compound of sodium with a phosphate counterion. It is used as a laxative and, in combination with other sodium phosphates, as a pH buffer.
What do you get if you mix sodium and sulphuric acid?
Mixing sodium and sulfuric acid would result in a reaction that produces sodium sulfate, hydrogen gas, and heat. The reaction is highly exothermic and can be potentially dangerous if not handled properly.
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.
When calculating the number of moles of solid Na2SO4 the factor used is?
The molar mass of anhydrous sodium sulfate is 142,04.
Why is anhydrous sodium sulfate used in organic chemistry labs?
Because of its affinity for water, anhydrous sodium sulfate is often used to dry hydrophobic solvents used in aqueous organic extractions. For example a water based sample is extracted for organic compounds using dichloromethane, or ethyl ether in a separatory funnel. The organic layer is passed through a buchner funnel holding anhydrous sodium sulfate, yielding dried solvent extract.
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 many grams of anhydrous sodium sulphate should be used to prepare Sodium sulphate solution 60ml where Each ml contains 0.1mmol of Na plus?
0.336g of anhydrous sodium sulphate
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.

How can you tell sodium hydroxide acted as a catalyst?
Sodium hydroxide anhydrous is used as a catalyst for the transesterification reactions of methanol and triglycerides.
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%.
What are sodium hydroxide and copper sulfate used to test for?
