How fast does hydrogen peroxide solution break down?
This depends on a variety of factors such as temperature, the strength of the hydrogen peroxide solution and the presence or not of a catalyst, like manganese dioxide or silver. Acidic solutions also exhibit better stability. So, a slightly acidic and weak solution of hydrogen peroxide, stored in a cool place, will break down the slowest. Hydrogen peroxide decomposes to form water and oxygen, liberating heat in the process.
Is hydrogen produced when copper reacts with silver nitrate?
No, the reaction is: 2AgNO3+Cu=Cu(NO3)2+2Ag
What is the reaction between silver and dilute nitric acid?
confusion
What is the reaction between cadmium chloride and silver chloride?
There would be no reaction because they are both chlorides.
What are 10 example of compounds?
Sodium Chloride Potassium Carbonate Sulphuric Acid Iron Oxide Nitrous Oxide Hydrogen Sulphate Lead Chloride Hydrogen Peroxide Silver Chloride Sodium Hydroxide.... 10 examples of chemical compounds.
What is the reaction product of Fentons reagent with silver?
The reaction product of Fenton's reagent (a solution of hydrogen peroxide and ferrous iron) with silver is typically silver oxide (AgO) or silver hydroxide (AgOH) depending on the conditions of the reaction. These products are formed when the silver ions present in the solution react with the hydroxyl radicals generated by Fenton's reagent.
How do you strip silver from copper using hydrogen peroxide?
you use your brain
What is the chemical reaction of hydrogen peroxide on brass?
Hydrogen peroxide is H2O2 (which you probably know) so its pretty much water with a extra Oxygen atom. Hydrogen peroxide is a unstable element and when disturbed it easily flings off the extra oxygen atom with quite a bit of heat and energy and initially turns into water and oxygen, that is why its used as a bleach because the oxygen flings off hitting dirt particles or colour particles. Back to your question, what silver does is it acts as a catalyst(if you don't know what a catalyst is read the next paragraph) causing this reaction to happen much faster, and alot more energy is released (since its happening alot faster), hydrogen peroxide used with silver can produce enough energy to power rockets hens why sometimes people call it rocket fuel (hydrogen peroxide is actually used in rockets) a catalyst is a substance that speeds up something but doesn't get consumed itself, it only helps the reaction. I personally believe that Hydrogen Peroxide will be a possiable fuel source for the future, I know it has easy potential to produce a car with 1500hp, I'm not a scientice so but I know theres few minor issues they need to overcome, China has produced a Hydrogen peroxide car(that runs solely on hydrogen peroxide)
Why do silver anklets turn black over time?
It is due to the formation of silver sulphide ,as a result of the reaction between silver and hydrogen sulphide in the air.
How hydrogen gas is using in the airjet jackets?
A hydrogen peroxide-powered motor is based on the decomposition reaction of hydrogen peroxide. Nearly pure (90% in the Bell Rocket Belt) hydrogen peroxide is used. Pure hydrogen peroxide is relatively stable, but in contact with the catalyst (for example, silver) it decomposes into a mixture of superheated steam and oxygen in less than 1/10 millisecond increasing in volume 5000 times: 2 H2O2 → 2 H2O + O2. The reaction is exothermic, i.e. with liberation of much heat (about 2500 kJ/kg), forming in this case a steam-gas mixture at 740 °C. This hot gas is used exclusively as the reaction mass and is directly led to one or more jet nozzles.
How does Hydrogen peroxide decomposes much faster in the presence of enzyme catalysts?
Try a peroxidase enzyme. For example "Versatile peroxidase", Jena Biosciences #EN-203L is an extremely effective catalyst.
Why is silver jewelry tarnishing a chemical change?
Because it is a reaction on the silver surface between silver and hydrogen sulphide (H2S); the result is the silver sulphide (Ag2S), a black compound.
Is tarnishing silver a chemical change?
Tarnish on silver is Silver Oxide, which is oxidised silver. This is indeed a chemical reaction.

How do you convert Silver oxide back to silver?
To properly dispose of Silver Oxide :• Add 100 volumes of distilled water to 1 volume Silver Oxide powder. (glass container only)• Add common household Hydrogen Peroxide, very slowly, with lots of stirring. (glass or plastic stirrer only)• Add Hydrogen Peroxide, stirring, until all of the Black Powder has turned gray. (lots of bubbles - Oxygen)• You now have reduced Silver Oxide into harmless Silver Powder. (You may want to keep it)• NOTE : Silver Powder also breaks down the Hydrogen Peroxide, forming Oxygen bubbles.
Why does silver turn black?
silvers turn black due to the reaction of sulphur present in hydrogen sulphide from air. --- Tarnish is silver oxide (rust) caused by a chemical reaction of oxygen and hydrogen sulphide with the surface of the silver. Unlike iron, silver will not rust in air absent of hydrogen sulphide.
Why is a silver platter tarnishing a physical property?
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
