Barium Peroxide, Sulfuric Acid: Iron, Potassium Permanganate

I've seen this one before. They way they do it is by switching the beakers when they're out of shot at 0:36. Nice trick though. It's amazing what they can do with magic these days.

hey whats that man, i read on chemistry that it was potassium manganate, but yo wrote permanganate

@EhtYlno

It is indeed permanganate and not manganate. The manganese in permanganate is in the +7 oxidation state, and thus is purple. The manganese in manganate would be in the +6 oxidation state, and would look green. Here, we are using permanganate.

is barium peroxide damaging to the hair, my henna contains this chemical

Technically, yes. It's an oxidising agent, and is used for bleaching. What I'm assuming it would do to your hair is bleach the hair itself while dying it the henna colour, which would not be oxidised by the barium peroxide. Either way, pretty much anything that you use to change your hair's colour or bounce is damaging to it. It's not really such a big deal, though, since hair is dead, and you're not modifying the living root.

i) H2SO4 + Ba(O2) --> H2O2 + BaSO4 (white pp)

Fe° + H2SO4 + H2O2 --> Fe(II) (greenish) + SO4(-II) + 2H2O

ii) H2SO4 + Ba(O2) --> H2O2 + BaSO4 (white pp)

2KMnO4 (intense violet) + 3H2SO4 + 5H2O2 --> 5O2 (gas) + 2MnSO4 (virtually colourless) + K2SO4 (colourless) + 8H2O

Isn't it?
