4 thoughts on “Is the hydrogen peroxide solution corrosion of gold?”

The chemical properties of gold are stable and have a strong corrosion resistance. They are generally not oxidized from room temperature to high temperature in the air. They are insoluble in strong acids such as a single hydrochloric acid, nitric acid, and sulfuric acid. That is the king water) to generate chlorine h [AUCL4]; when aerobic existence at room temperature, gold is soluble in a solution containing potassium cyanide or sodium cyanide to form a stable complex M [AU (CN) 2]; It is soluble in solution with sulfur sulfur; it is also dissolved in acidic solutions with chlorine gas. Gold does not work with alkali solution, but it can be generated with sodium peroxide when melting. The combined price of gold is -1, -2, 1, 2, 3, 5, 7, etc. Oxide has a triple oxidation two gold AU2O3, and chloride has a three-chloride gold AUCL3. In an acidic medium, chlorine h [AUCL4] or a complex m [AU (CN) 2] can be restored to metal zinc (zinc powder or zinc wire), sodium sulfate, hydraulic pheasant, etc. The sulfide will corrode gold and generate soluble sulfide gold. Exic acids in the soil and metabolites of certain bacteria can also dissolve trace gold. So gold will not be corroded by hydrogen peroxide. Hope it helps you
No. The concentration of hydrogen peroxide is only 30%, and the concentration of hydrogen peroxide does not have concentrated sulfuric acid. Highness of nitric acid. Concentrated sulfuric acid cannot be corroded. Water and a super -strong acid can corrode gold. (I hope it will help you)

No, gold is generally dissolved in hydrofluoric acid or acidic acid
Sorry, I read the problem wrong
