ammonium sulfate, solution - Introduction. Specific gravity 1.769. Decomposition at 235 ℃. Easily soluble in water, the aqueous solution is acidic, insoluble in ethanol and acetone. In humid air, it will absorb water and agglomate, and interact with alkalis to release ammonia.. When burning, it is decomposed into ammonia and sulfuric acid.

Mohr's salt is prepared by dissolving an equal amount of mixture of hydrated ferrous sulphate and ammonium sulphate in water that contains sulphuric acid. This results in the solution to crystallization, therefore the solution …

 · A traditional fertiliser, Sulphate of Ammonia should be applied evenly at the recommended rate and hoed into the top surface of the soil. If the soil is dry, it should be well watered in. Sulphate of Ammonia should not be left on leaves or stems, it should be lightly brushed off onto the surrounding growing media.

 · 70.6 g/100 mL (0 °C) and. 103.8 g/100 mL (100 °C) and the protocol says I need use 85% ammonium sulphate to dissovle some reagents. So I think it is supposed 85g can be dissolved in some quantity of water (which makes the total volume to 100ml). But anyway, I found I could not make it out. -Drlongwood-.

Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all of the water …

Prepare 800 mL of distilled water in a suitable container. Add 761 g of ammonium sulfate to the solution. Dissolve with stirring and gentle heating. Cool to room temperature and adjust the pH to 7 (with NH4OH or an acid such as HCl). If excess is to be stored, sterilize the solution by filtering through a 0.2-µm filter and store at 4°C.

It is generally used as a saturated aqueous solution which is diluted to the required concentration and expressed as a percentage concentration of the saturated solution (a solution). While ammonium sulfate fractionation is a low resolution technique, it is used successfully to reduce the complexity and decrease the sample volume on a
