Title: Can anyone balance this equation?
Post by: Locker on June 20, 2012, 04:14 pm
Been trying to work on this for a while, think i may have it balanced but this is the hardest thing I've done in a loooong time 8)
This is the equation anyway, took me 6 sheets of A4 paper to finally get an answer ;D:

K4Fe(CN)6 + H2SO4 + KMnO4 --> Fe2(SO4)3 + K2SO4 + MnSO4 + HNO3 + CO2 + H2O

Note: This is without the ozone.
Ill put my answer on here in a bit, want to let some of the smart people that i know are on silk road have a go. ;)

Have fun, ::)

10 K4Fe(CN)6 + 218 H2SO4 + 122 KMnO4 -> 5Fe2(SO4)3 + 81 K2SO4 + 122 MnSO4 + 60 HNO3 + 60 CO2 + 188 H20

Duck is right.

With bigger numbers it's more of an exercise in mental masturbation than anything that augments your understanding of chemistry.
Apps exist for larger numbers to make your life easier (webqc.org/balance.php)
