akcapr Posted April 22, 2005 Share Posted April 22, 2005 Heres the story. I was bored so i put ammonia and sulfuric acid into test tube hoping some ammonium sulfate would be made. A day later i took that mix and pored it in a steel pan i ususally dry my chems in. After a day in the pan i looked and WOW! it turned greenish blue, and had brownish grayish little liooked like turning things in there. The bottom of the pan was nice and clean, compared to the sides which were maore grey- the bottom turned lighter gray. The orange color on the base of the pan disappeared but was left on the sides (the color form heating iron oxide in it). im not sure what the reaction was. Does anyone know? heres pics of what the pan looked like: Link to comment Share on other sites More sharing options...
H2SO4 Posted April 23, 2005 Share Posted April 23, 2005 i have no clue. I mixed copper sulfate and ammonia before and it makes a blue gellish mass also. I have no clue. Kinda wierd. Link to comment Share on other sites More sharing options...
budullewraagh Posted April 23, 2005 Share Posted April 23, 2005 ok, did you measure the amounts of ammonia and sulfuric acid before? if you have a 1:1 ratio, you have the bisulfate. if you have a 2:1 ratio you have the sulfate. what sort of ammonia and sulfuric did you use? store brand? did you titrate? i think your solution had a displacement reaction with the pan. try again and use indicators. test for ammonia gas being released.

akcapr Posted April 23, 2005 Author Share Posted April 23, 2005 i was in my boxers ready to go to bed when i did it. The ammonia (dont even know the conc. ) was sitting out so i got a qucick idea and did the above in liek 30 sec. The h2so4 was 95% but i dont know how much of each i put in. If you could at least, try to see what possible could have happened. Link to comment Share on other sites More sharing options...
YT2095 Posted April 23, 2005 Share Posted April 23, 2005 Tetramine Iron II Sulphate is the blueish stuff. Link to comment Share on other sites More sharing options...
Primarygun Posted April 23, 2005 Share Posted April 23, 2005 Is displacement reaction a kind of oxidation and reduction? Link to comment Share on other sites More sharing options...
budullewraagh Posted April 23, 2005 Share Posted April 23, 2005 sometimes it is. ex: Al+Fe2O3-->Al2O3+Fe sometimes it isnt ex: 2LiCl+RbF-->RbCl+LiF akcapr, im almost positive you had a fairly acidic solution. in the future use glass and by all means, measure your reactants!

akcapr Posted April 23, 2005 Author Share Posted April 23, 2005 so does anyone know the full reaction equation(s)? and by the way, what is the tetramine iron II sulphate stuff? Link to comment Share on other sites More sharing options...
budullewraagh Posted April 23, 2005 Share Posted April 23, 2005 it's FeSO4 complexed with NH3 Link to comment Share on other sites More sharing options...
