(a) A few drops of freshly prepared iron (II) sulphate solution were added to potassium nitrate solution in a test-tube. Concentrated sulphuric (VI) acid was then carefully added to the mixture. State the observations that were made. (b) Write an equation for the reaction that occurs when solid potassium nitrate is strongly heated. 7.
For preparation of 100.00g of iron(II)-ammonium sulfate hexahydrate. а 70.90g of iron(II) sulfate heptahydrate. and 33.70g of ammonium sulfate is required. Dissolve compounds in hot water apart and then mix ... W.Guenther, Ammonium iron(II) sulphate hexahydrate.
I prepared 0.01 M FeSO4.7H2O stock solution by adding 2.8g of the solid to 1 ml conc sulfuric acid, stir, then add to water. Dilute to 1 L. Always add acid to water. Cite. 3 Recommendations.
Preparation. For medical purposes, this salt should be prepared by heating together dilute sulphuric acid and iron wire.The iron is oxidized at the expense of the water, hydrogen escaping with effervescence; while the acid unites with the oxide to form the sulphate of the protoxide, which remains in solution. In order that there may be no admixture of the sesquioxide, which it is desirable to ...
F e+H 2 SO4 →F eSO4 +H 2 . When 1 mole iron reacts with 1 mole of sulphuric acid, then 1 mole of ferrous sulphate is formed with the evolution of hydrogen gas. Hence, option A is correct.

Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 Fe(SO 4) 2 (H 2 O) 6.Containing two different cations, Fe 2+ and NH 4 +, it is classified as a double salt of ferrous sulfate and ammonium sulfate.It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation by air.
26-08-2007· Ferrous or iron(II) compounds can easily be oxidised to ferric or iron(III) compounds, when exposed to air. So iron(II) sulphate which is stored for some time will have iron(III) sulphate present.
Sulphuric acid + iron (II) sulphate. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). All concentrations are given in weight-% and the solvent is ...
