Making Iron(II) Sulfate | Urgent

Basically, I'm doing a lab research and I'm short in FeSO4. I need a way to make it, don't worry with the purification part, I just need a north to look. Already tried to react FeCl3 with H2SO4 but it made iron(III) sulfate The lab has some reagents including: Some old iron(II) sulfate that's yellow...

Polymer Synthesis using bioproducts

My and the boys are researching polymers, we found some articles but weren't so clear, my question is what organic proteins (animal, fruit, etc) we can use to produce polymers?

Nanoparticles synthesis

Im researching nanoparticles synthesis and I've some questions. By now I only know the turkevich method, I would like to know other methods to produce metal nanoparticles. And about the turkevic method,can it be applied to other metals besides gold and silver? and how can i measure the nanoparticles...

Thanks for the explanation, but why i can't use (12 x 96500)? i thought it was based on the balancing and not on just 1 mol of Al. Your results matched perfectly. :D edit: i guess i figured it out. when I do 135000 x 28800 x 27 / (12x96500) I'm saying that 1mol of Al is receiving 12mols of electrons...

Question about aluminium electrolysis (little complex)

First of all, I'm not a native english speaker, some terms maybe a little off Basically, my professor asked how much liters of oxigen are produced based on an aluminium electrolysis in an industrial process, this is the equation: 2Al2O3 = 4Al + 3O2 This electrolysis was done at 900Celsius, using gra...

Ok Buddy. Iron is able to have different oxidation numbers. Basically + 2 and +3 In the First experiment iron goes from 0 to +2 by adding an acid in this case acetic acid (vinegar). Fe + 2 H+ => Fe2+ + H2 In the second test he add peroxide an oxidizer The oxidation number change from +2 to + 3. 2 F...

Need help whit iron redox

First of all, if i wrote anything wrong, feel free to correct me. Hey guys, hope you good, My teacher did some reactions using iron, but i didn't get everything right. He used steel wool, hydrogen peroxide, H+ from ethanoic acid from vinegar and hypochlorite from solution. On the first reaction he a...
