@MakeGold aqua regia is a mixture of nitric acid and hydrochloric acid. The following are the general steps to make aqua regia: Choose a suitable container: Aqua regia is highly corrosive and can dissolve many materials. Therefore, you should choose a container made of glass or plastic that can withstand the acidity of the mixture. Add the acids: Add one part concentrated nitric acid to three parts concentrated hydrochloric acid in the container. Mix the acids: Stir the mixture thoroughly using a glass or plastic stirrer. Be careful not to splash the mixture, as it can cause burns. Use the mixture: Aqua regia is highly reactive and should be used immediately after preparation. Do not store the mixture in a sealed container, as it can build up pressure and cause an explosion. Please note that aqua regia is a hazardous substance and should be handled with extreme caution.
