Chemistry question Anyone know how solve it?
Names would be helpful.
K4Fe(CN) + KMnO4 + H2SO4= ???
Thankx
The cyanide needs increased to 6 molecules. (It is not “poisonous” enough to balance the equation).
$$\underbrace {\ 10K_4Fe(CN)_6 } _ {Potassium ferrocyanide }\ +\underbrace{122KMnO_4}_{Potassium\ permanganate}\ +\ \ \underbrace{199H_2SO_4}_{Sulphuric\ acid}\\\\
\Rightarrow \ \underbrace{162KHSO_4}_{Potassium\ bisulphate}\ +\ \ \underbrace {5Fe_2(SO_4)_3}_{ferric \ sulphate}\ \ \ +\ \underbrace {122MnSO_4}_{Manganese(II) sulphate}\ +\ \ \underbrace {60HNO_3}_{Nitric\ acid}\ \\\\
\ +\ \underbrace {60CO_2}_{Carbon\ dioxide}\ +\ \ \underbrace {188H_2O}_{water} \\$$

It is a pretty tough one to balance. Here is a helpful website:

Ah, trying to slip some cyanide into the forum, are you DavidQD??? Well, you won't get rid of us that easily.........we're too crafty to fall for such a ruse....!!!!
{ BTW.....an impressive dispaly of LaTex !!!! }
Thank you CPhill. How many imperial minims in a minimum daily requirement of CN?
I am impressed too !!!!
Looks like you have quite a fan club David.
(I found these Chris, you just leave them lying around everywhere. Finders keepers! )
Ginger your post is very colourful and arty, a little French in origin perhaps?
Your grand total of 2 points looks a little pathetic so I will more than double your points for you.
It is not often that one of my thumbs can have such a dramatic effect.
But, this is the magical land of Camelot, and I am the Lady of the Land.
