It is recommended to prepare ferrous ammonium sulphate solution in acidic medium because iron when combined with water gives the precipitates of oxides of Iron.
You have to dissolve this in an amount of water and stirr it gently. It is a very well soluble salt.
It's prepared by dissolving ferrous and ammonium sulphate in water with some sulphuric acid and recrystallising. For details please see the wikipedia article about ammonium iron (II) sulfate.
A solution of ammonia can be used to prepare ammoniumsulfate by reacting it with a solution of sulfuric acid to produce a solution of ammonium sulfate, which can be dried if desired to prepare solid ammonium sulfate.
This depends on the concentration of the primary solution; for a 25 % ammonium hydroxide solution you need 85,15 mL.
Add ferrous chloride solid to saturated aqueous solution of oxalic acid then to expel the HCl gas then saturated solution is allow to cool the crystals of ferrous oxalate settled down with in few minutes remove the excess liquid and get the dry compound.

Mix ammonia with a solution of hydrochloric acid, then evaporate the solution. The remaining salt is what you want.

To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
To prepare the buffer using solid form reagents, prepare a 0.1 M ammonium acetate solution by dissolving 7.7 g ammonium acetate in a 1000 ml water. Adjust 1 L of this solution to pH 4.5 by adding acetic acid (about 8 ml) and 5 ml of 1 M p-TSA (equivalent to 5 mM p-TSA).
Ammonium molybdate is (NH4)2MoO4. Its molar mass is 148g/mol. A 0.5M solution will have half a mole per liter of water. Half a mole of ammonium molybdate is 74g, so you would measure out 74g of it, and dissolve it in a liter of water.

H2SO4 (30%-40%) added slowly to steel wool. The pH of the solution should be acidic at any given time, otherwise the ferrous ions will oxidize to the ferric state. The sulfuric acid will begin to dissolve the steel, producing hydrogen gaz.
