platinum is a metal. i dont think it can exist as an acid. hope this helped
Platinum does not react with sulfuric acid under normal conditions.
"Platinum resists sulfuric acid in all concentrations and temperatures."Source: Handbook of Corrosion Data - 2nd Edition, p. 850, ASM International, Materials Park, Ohio, 1995, ISBN: 0-87170-518-4
Platinum doesn't react with nitric acid.
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.
acid.
Platinum is not destroyed by nitric acid.
Hydrochloric acid has a more dramatic effect on palladium compared to platinum. Palladium forms soluble complexes with hydrochloric acid, while platinum is more resistant to attack and does not readily form soluble compounds with hydrochloric 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.
Platinum is resistant to most acids, but it can dissolve in a mixture of hydrochloric acid (HCl) and nitric acid (HNO3), known as aqua regia. Aqua regia can effectively dissolve platinum by forming soluble platinum complexes. Additionally, platinum can be attacked by certain halogen acids, such as chlorine and bromine, under specific conditions.
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.
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.
because it produces Chloroauric acid Which has corrosive to gold and platinum
