not natural compound, salt the bivalyellowcomic.comt transitional metal iron and also inorganic nitric acid. Indigenous water options crystallizes as hexahydrate and nonahydrate.


Reaction iron(II) oxide, sulfide, hydroxide or hydroxycarbonate and also nitric acid

chemical equation:

FeO + 2HNO3 = Fe(NO3)2 + H2O FeS + 2HNO3 = Fe(NO3)2 + H2S↑ Fe(OH)2 + 2HNO3 = Fe(NO3)2 + 2H2O Fe2CO3(OH)2 + 4HNO3 = 2Fe(NO3)2 + CO2↑ + 3H2O
а 24.95g that iron(II) oxide or 30.53g that sulfide or 31.21g the hydroxide or 35.72g of hydroxycarbonate and 67.33g that 65%
Add mountain to the flask, add little parts of iron compound through stirring until it will completely dissolve or, if you usage carbonate, until carbon dioxide emission will stop. After reaction will certainly stop, filter the solution and use the for decision growing.

Reaction metal iron and diluted nitric acid

Chemical equation:

4Fe + 10HNO3 = 4Fe(NO3)2 + NH4NO2 + 3H2O
Add cold diluted acid equipment to the flask, include iron pieces, shavings or powder and stir it until gas emission will certainly stop.

Reaction iron(II) sulfate and calcium or lead(II) nitrate

You deserve to use steel chloride rather of sulfate if you usage lead salt.Chemical equation:

FeSO4 + Ca(NO3)2 = CaSO4↓ + Fe(NO3)2 FeSO4 + Pb(NO3)2 = PbSO4↓ + Fe(NO3)2 FeCl2 + Pb(NO3)2 = PbCl2↓ + Fe(NO3)2
Add to the flask v calcium or command nitrate solution little parts of steel salt solution and stir. The huge amount of poorly soluble precipitate will certainly form. Resolve it out and discard, filter the systems carefully.

Reaction iron(II) hydroxide or hydroxycarbonate and also ammonium nitrate

Chemical equation:

Fe(OH)2 + 2NH4NO3 = Fe(NO3)2 + 2H2O + 2NH3↑ Fe2CO3(OH)2 + 4NH4NO3 = 2Fe(NO3)2 + 3H2O + 2NH3↑ + CO2↑
а 31.21g of iron(II) hydroxide or 35.72g the hydroxycarbonate and also 55.60g that ammonium nitrate is required.
Add come the flask suspyellowcomic.comded in water stole compound and add tiny parts of warm ammonium nitrate systems with heating and stirring. Emissions of large amount the ammonia will begin.Attyellowcomic.comtion, exuding ammonia irritates eyes and also lungs! The synthesis have to be lugged out just in a fume hood or outdoors!


The systems absorbs humidity from the air, so expansion is tough yellowcomic.comough.

Storage conditions

store in the original form or under numerous layers that varnish at mean humidity and also room temperature. Perform not keep in matchboxes or noodle wool and also do not heat.
