Gold and platinum are dissolved by Aqua regia
Gold and platinum are two precious metals that can be dissolved by Aqua regia, a highly corrosive mixture of nitric acid and hydrochloric acid. This solution is commonly used in the process of refining and cleaning these metals, as it can break down their molecular structures and allow for easier separation and purification.
Gold and platinum are dissolved by Aqua regia because of their unique chemical properties. While many other metals are resistant to this solution, gold and platinum are particularly susceptible due to their lack of reactivity and resistance to oxidation. This makes them ideal candidates for dissolution in Aqua regia, as it can effectively break down their molecular bonds and allow for the extraction of pure metal.
Overall, Aqua regia is a powerful tool in the world of metallurgy and refining, particularly when it comes to working with precious metals like gold and platinum. Its ability to dissolve these metals makes it a valuable resource for jewelers, refiners, and other professionals who work with these materials on a regular basis.
