What metals brake up hydrogen peroxide?

Manganese and manganese dioxide. Also potassium iodide does a good job.

H-O-O-H\n\nThere are NO double bonds in hydrogen peroxide.  If there were, the molecule would be charged.  If you don't believe me, check the link.

They are chemically different. Neither one should be put directly on scrapes- especially alcohol- it will burn like fire and irritate the tissues. Hydrogen peroxide can be used in a diluted form as long as you rinse it off.

If you want to identify brass versus gold, try using some ammonia solution or vinegar on the metal. Brass has oxides which will be dissolved and the brass will come out much brighter. Gold does not oxidize and will not react. Highly polished brass will not have an oxide coat to remove, so you can test it by immersing it in a solution with 2/3 vinegar and 1/3 hydrogen peroxide solution, and leave it for more than fifteen minutes. If it is brass and not gold, the solution will begin to turn green as the copper in the brass begins to dissolve. Again, gold will not react.

Potassium manganate or potassium permanganate?  And I'm assuming a solution of iron(II).\n\nBeyond the corrosivity of the sulfuric acid, and the oxidizing capability of the manganese species, as well as its ability to stain EVERYTHING, there are no additional hazards.  Permanganate stains can be removed by addition of an hydroxylamine solution (either the sulfate or the chloride).

A stabilizer is often necessary when using H2O2, because that compound tends to decompose, especially in the presence of trace amounts of many metallic ions.  In fact, if even a minute amount of, say, Cu++ is present, the decomposition can be violent.

What peroxide? Hydrogen peroxide es colorless

crest white strips and Listerine whitening mouthwash in between..don't get carried away with whitening though, the peroxide can damage your enamel

Caramide peroxide...which is stabilized hydrogen peroxide with urea. \n\nIt must have its appropiate surfactant, to make it effective....these are trade secrets, and you won't find much data on theses, but often they use a sorbitan ester.

Now, THAT is what I call a challenging question! It requires some thinking in addition to the book-ish knowledge and I love it! But, before I continue with my answer, I'd just like to correct one statement:- "I know that peroxide reacts with metals and glass", It does NOT. Metals and glass act as catalysts i.e. they accelerate the reaction of conversion of Peroxide into Water and Oxygen but they don't participate in the reaction.\n\nNow coming to your question, the varying levels of fumes that you are observing have nothing to do with an organic reaction.\n\nLet's address all your situations one-by-one:\n======= ========== ============\n1- When you pour it around the faucet and it bubbles furiously around the crud and not on the spigot itself.\nThe reaction going on in there is the same ol' Peroxide converting to Water and Oxygen.\nOne molecule of Peroxide (liquid) ----> One molecule of Water (Liquid) + Half molecule of Oxygen (gaseous)\n\nWhich is Symbolically-\nH202 (l) -------> H2O (l) + (1/2)O2 (g)\n\nIt's just that the reaction takes place at a faster rate around the crud around the base! \n\nIn general, ANY rough surface acts as a CATALYST for this reaction. Try it yourself, put some peroxide on a smooth surface and then put some on a rough surface. You can easily see that it fumes and bubbles more on a rough surface. It is because on a rough surface there is more AMOUNT of surface on a given area due to all the unevenness of the surface. And more area accomodates more peroxide which leads to more reaction for a given area and hence a faster rate.\n\n======= ========== ============\n2. When you drop earings into peroxide, the whole earings don't bubble only the "gunk" does and when that's gone it stops!\n\nHmm.. This required a little bit of thought process: The "gunk" in your earrings can be two things-\na) Deposition of Dust or dead skin-\nIf this is the case, then the answer would be- "Rough surfaces and dust CATALYZE the reaction of conversion of Perxide into Water and Oxygen which I have already metioned."\n\nb) Deposition of METAL OXIDE because of rusting or corrosion  or tarnishing of your earring.\nNow, if THIS is the case, then the bubbles are coming out due to the REDUCTION reaction by peroxide in the acidic medium.\nLet's see what's happening in there-\nThe Metal Oxide on the surface of your metal earrings is an oxidising agent i.e. it releases Oxygen (Oxygen atom). In presence of an oxidising agent, the Peroxide acts as a reducing agent. It reacts with the oxygen atom like this-\n\nH2O2 (Peroxide) + [O] (Oxygen atom from the rust) -----> H20 (Water) + O2 (Oxygen molecule)\n\nYou can see that Oxygen is being released here, THAT CAUSES THE BUBBLES!\n\n======= ========== ============\n3- It bubbles on cuts but, not on normal skin!\nWhoa whoa whoa... Don't put it on your skin, the reaction of it's conversion to water is exothermic (gives out heat) and sometimes, explosive!\nNow, to answer the question, it might be the tiny dust particles in your abrasion that could be triggerin' off the decomposition reaction & causing the release of Oxygen gas bubbles \nOR as you might be knowing that the pH of the blood is MORE THAN 7, i.e. it is basic or alkaline in nature AND in alkaline solution, this reaction takes place-\nFerrous(Iron) Ions (Fe +3) + Peroxide (H2O2) + Hydroxyl Ions (OH-) ----------> Ferric (Iron) Ions (Fe 2+) + Water (H20) + OXygen Molecules\n\nDid you see that? One of the products in the reaction up there was Oxygen molecules!! Now, that means that we are gonna have some bubbles there as Oxygen gas is gonna bubble baby!\n\nP.S. This is perhaps the longest answer I have ever typed in my entire life!

Peroxide bubbles because of the presence of a substance called catalase; which is a chemical found in your blood and in the cells of your body.  What catalase does is help speed up the chemical reaction which changes peroxide from H2O2 to H2O - water - and the chemical reaction taking place is what forms the bubbles.

Hydrogen peroxide will help kill most bacteria when used to clean an injury. It will also kill some live tissue, but so will a bacterial infection (which would probably damage more tissue than would cleaning the wound in the first place). In the future, just use enough to clean the wound, or, if you are wary about using hydrogen peroxide, you may purchase something like foaming antiseptic made by the Band-Aid company, which works well.

Sodium, Potassium, Barium\n\n As long as the metal is more reactive than magnesium, it will be able to displace magnesium ion.

Well, metal oxides dissociate in water, forming the O-2 ion. This is so extraordinarily basic that it doesn't exist. The splitsecond it's created, it grabs a hydrogen from the surrounding water and forms two OH- ions.

Hi. Iron, carbon, silicon, copper, oxygen (as part of silicon dioxide), hydrogen (as part of plastic).
