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 added some steel wool to a glass and added the vinegar, he explained that the iron went from Fe0 to Fe2+, cause of the H+.
Code: Select all
Fe + H+ = Fe 2+ + H2
On another glass he added some steel wool and some hypochlorite solution, straight away nothing happened, but then he adds some vinegar, and it went slowly to Fe3+ (only got this part cause of the color), but again, don't know why and how.
He also asked the cell potential of those reactions, if someone could help with this too, would be very grateful, thanks.
