That story about putting permanganate in the fish tank is actually quite interesting. Potassium permanganate is actually used to treat protazoa infections in fish sometimes. :)

[@goytabr]

I used it in a dilute solution to bathe my feet when I had an open-wound foot infection that was very painful and was preventing me from walking properly. It stained my feet brown for weeks (it's purple, but oddly, it stains the skin brown, sort of like iodine), but it was very effective.

[@xBenjourx]

+Georgia Millis It is very interesting! I'm surprised all the fish didn't die... In minute quantities it'll bump off bacteria hence treating the infections but otherwise it's VERY toxic to aquatic life! +Goytá F. Villela Jr. It'll do that because it's such a strong oxidising agent. It is essentially decomposing to MnO2 on the surface/in crevices of the skin which is a strong brown colour. Glad it sorted the issue though!

[@lokalnyork]

+Georgia Millis There are several "baths" for fish You can buy in pet shops, I've seen my dad using blue and green. They probably have some salts of manganese and other metals in them.

[@goytabr]

Ben Harrison, the copper-based blood pigment is *haemocyanin* and no fish (or any vertebrates for that matter) have it, only some mollusks and arthropods (crustaceans and arachnids, including a few land species). I would guess that the green stuff Local Ork mentioned was *malachite green* (or some commercial mixture containing it). Malachite is the name of a green copper-containing rock, but malachite green is an organic dye just named after that rock's color and contains no copper. Malachite green is used as an antimicrobial in aquaculture, but it's a problem when used in commercial fish farming intended for human consumption, because some toxic metabolites remain in the fish flesh.

[@xBenjourx]

+Goytá F. Villela Jr. Of course it is, my mistake! Thanks for the correction! I knew it was in molluscs such as sea-snails/crabs/lobsters etc. and was sure I'd heard it stretched to other aquatic life eg. some fish etc. Interesting about the malachite green/malachite difference. I would have thought it confusing to call them such similar things. I guess for 'scientists' the IUPAC names are suitably different. I'm sure that was an issue with azo/azide dyes or similar? They were accumulating in fish meat sold on stalls in Chinese marketplaces (If I remember correctly) but resulting chemicals (whether it the dye or a metabolite of) were at levels which could pose as a toxic hazard to humans.

Isn't potassium permanganate used to treat several diseases fish can get, anyway? Sounds like Granddad knew a lot more about fish than he let on.

[@deralmighty8011]

jazztom86 I view it more as like a vitamin supplement.

[@bobrianfo104]

Some fish like corydoras or botias are very sensitive to those products, I had some in an acquarium with a couple of ill fish and the treatment caused them to die. It really depends from the kind of fish and the amount you give them. Bottom dwellers get more damaged because of the different concentration of the product, fish that live right below the surface like betta splendens or trichogasters (gourami) would barely even care unless the dosage gets very extreme.

[@elephystry]

Probably has to do with the size of the fish.

[@Calilasseia]

Yes, potassium permanganate was used as a fish disease treatment many years ago, before better agents were developed. Because potassium permanganate is a powerful oxidising agent, it kills the micro-organisms responsible for several aquarium fish diseases. However, it's a very BAD idea to introduce this substance into a tank containing scaleless fish, such as loaches or catfishes. These fishes are far more sensitive to the effects of this chemical, and will die if subject to prolonged exposure thereto. However, if you want to sterilise an aquarium BEFORE putting fish into it, potassium permanganate does the job nicely. Just make sure ALL residues are removed before adding the fish, if you're going to house loaches or catfishes in that aquarium. :)

[@lalaithan]

Also used to clear up a cloudy tank. It's perfectly fine to use if you use it carefully. It messes with the oxygen in the water.

[@louistournas120]

I guess the equation is 2 KMnO4 + 3 H2SO4 + H2O2 → 2 MnSO4 + 4 H2O + K2SO4 + 3 O2 The Manganese in permanganate gets reduced from 7+ to 2+. The Hydrogen in H2O2 gets oxidized to 1+. #chemistry #man. #It #is #the #best.

[@michaelowenplayer]

Chemistry is, indeed, the BEST !

[@Ildarioon]

Not quite. The reason we add sulfuric acid is to create free H+, because MnO4- reacts like that MnO4-(purple) + 8 H+ + 5 e- --> Mn2+(incolour) + 4 H2O. The equation for the whole reaction is: 2 MnO4- + 5 H2O2 + 6 H+ --> 2 Mn2+ + 8 H2O + 5 O2

[@louistournas120]

Ildarioon That's weird. Your equation ends up as 2 KMnO4 + 3 H2SO4 + 5 H2O2 → 2 MnSO4 + 8 H2O + K2SO4 + 5 O2 and mine is 2 KMnO4 + 3 H2SO4 + H2O2 → 2 MnSO4 + 4 H2O + K2SO4 + 3 O2 What went wrong?

[@Ildarioon]

louis tournas First, writing "MnSO4" and "K2SO4" is false in solution but more than that, it's a source of confusion. If you actually count the the elements will see that the numbers of oxygen and hydrogen you put in both sides aren't the same.

[@louistournas120]

Shouldn't that Hydrogen Peroxide be stored in a dark, opaque container to keep the light from decomposing it faster?

I think amber glass and no sunlight does the trick fine.

[@sifuculreif6448]

Yeah, but both of those bottles were white and partly translucent.

They would either be used fast enough that it doesn't matter too much, or they would be stored in a dark chemistry store room/inside a dark cabinet inside a store room.

[@sifuculreif6448]

Sean Junkin mostly I'm saying this because the guy in the video was talking about how you have to use it quickly before it "goes off"(expires) and becomes water and oxygen. THEN I noticed he's got the stuff in white, translucent containers. I happen to know that H2O2 lasts longer if you keep it out of the light. That is all.

I'd like an explanation for why the color wouldn't disappear with a substantial pouring of H2O2, but DID disappear with only a small remnant of that very same H2O2.

[@Ishraqalshabab]

GetMeThere1 I'm not entirely sure, but it is likely that the amount of peroxide didn't have anything to do with it. The reaction was probably more reliant on the addition of the sulphuric acid, and as we saw he didn't add too much the first time.

[@GetMeThere1]

***** All true -- which has nothing to do with the fact that this reaction is known to occur easily at RT.

[@SIenderplier]

GetMeThere1 At 1:08 he says the Hydrogen Peroxide may be "flat" and at 1:18 explains that it had decomposed into oxygen and water, so im assuming it was mostly water being added the first time hence the reaction didn't occur. At least that's what I understood :P

4:14 This reaction reminds me of this reaction I did in an entry level chemistry course at college, I think it was called titration. I don't remember what the compounds involved were, but we had a vial of a clear solution, and long burette with what i believe was a pinkish-purple solution in it. The challenge was to put just enough of the solution in the burette into the beaker that the solution in the beaker turned a vibrant purple color. It was extremely tedious because you needed a very specific amount, and up until the point where you had the right amount it would behave just like the reaction with the video, with a splash of pink appearing in the beaker every time you added another drop of solution, and then quickly disappearing. It was worth it though, because the instant that you added the last drop and made the mixture just so, the entire beaker would suddenly go bright purple. Another thing that made it annoying was that if you added even a drop more than that, the mixture would change color again and the solution would be ruined, and you would have to start all over again, a process which took maybe 10 minutes or so, adding solution drop by drop.

My chemistry teacher in high school once told a story of how someone stole a small bottle of Potassium Permanganate and emptied it into the school indoor swimming pool. The color of this compound is so strong that even the small bottle in the huge pool turned the whole thing bright pink-purple. The school was going to spend an enormous amount of money to have the pool emptied and cleaned, but he stopped them, ran down to the local pharmacy, bought all the vitamin C supplements they had, and dumped it into the pool. The vitamin C converts the permanganate to regular managanate, and the potassium salt is an insoluble brown solid, which precipitated out of the water and was vacuumed off the bottom of the pool with a regular, far less expensive cleaning.

No, titration is used to determine an unknown concentration of a known analyte (Or 'Component' if that word suits you better) For example, Vitamin C, you can find it's concentration by adding a Redox titration like Dichlorophenolindophenol, which is a blue dye that will turn colorless when reduced by the Vitamin C. But that is just 1 of many forms of titration.
