Aqua Regia (HCL+Nitirc acid)
Pt+4HNO3+6HCl=H2PtCl6+4NO2+4H2O
heat is necessary
No. Aqua regia is used to dissolve noble metals: gold and platinum. It does not affect diamond.
Aqua regia is a mixture of nitric acid and hydrochloric acid that can dissolve platinum. It is commonly used in the refining and extraction of platinum and other precious metals due to its ability to break down their structure.
because the atomic structure is so dense it breaks through the dimensions and calls upon the gods for dissolving powers. then it takes an epic journey and becomes enlightened and melts through reality
Gold wouldn't corrode, I think that's what you mean because generally speaking metals don't dissolve. Corrosion is a chemical reaction where as dissolving is, I would say, more of a physical change because electrons aren't shared or exchanged in the process.Also platinum wouldn't.
The reaction of aqua regia is exothermic because it releases heat when the acids interact with metals, causing a very strong and aggressive reaction that can dissolve gold and platinum.
No.
acid.
Platinum does not dissolve in nitric acid, which is why it is commonly used in jewelry and other applications that require resistance to corrosion.
Nitric acid can dissolve iron but not gold, platinum, and palladium. Nitric acid is a powerful oxidizing agent that reacts with iron to form soluble iron nitrate, while it does not react with noble metals like gold, platinum, and palladium.

Sulfuric acid is a highly corrosive acid that can dissolve many substances, but it does not dissolve certain materials like Teflon (polytetrafluoroethylene), gold, platinum, and some types of ceramics.
Platinum can be extracted from catalytic converters by first crushing the converters to a fine powder. Then, the powder is mixed with a strong acid to dissolve the platinum. The platinum is then separated from the acid solution using chemical processes, such as precipitation or electrolysis.
Yes, many of them, certainly including gold and all the platinum group.
One example of a solid that is malleable and does not dissolve in water is gold. Gold is a metal that can be easily shaped without breaking, making it malleable, and it does not react with water, so it does not dissolve in it.
Platinum is extracted from a catalytic converter by first removing the converter from the vehicle. The converter is then crushed and heated to high temperatures to burn off any organic materials. The remaining material is then treated with chemicals to dissolve the platinum, which can then be separated and purified.
Sulfuric acid cannot dissolve certain non-metallic materials, such as Teflon (polytetrafluoroethylene) and some plastics like polyethylene and polypropylene. It also has limited ability to dissolve noble metals like gold and platinum. Additionally, sulfuric acid may not dissolve certain organic compounds with strong chemical bonds.
