What is Aqua Regia?
Aqua Regia is a mixture of hydrochloric acid and nitric acid. It is a very strong acid that can dissolve gold and other precious metals.
Manufacturing of Aqua Regia
Aqua Regia is a mixture of concentrated nitric acid and hydrochloric acid. The acids are mixed in a 1:3 ratio. Aqua Regia is used to dissolve gold and other precious metals.
Uses of Aqua regia
- Aqua regia is a mixture of hydrochloric acid and nitric acid, which is used to dissolve gold.
- The hydrochloric acid dissolves the gold, and the nitric acid dissolves the other metals in the gold.
- Aqua regia is a mixture of nitric acid and hydrochloric acid. It is a very strong acid that can dissolve metals such as gold and platinum.
- Aqua regia is used in the mining industry to extract these metals from their ores.
- It is also used in the laboratory to dissolve other metals and to clean glassware.
Acid that Dissolves Gold
An acid that dissolves gold is hydrochloric acid. Gold is a precious metal that is resistant to corrosion and oxidation, but it is soluble in hydrochloric acid. When a piece of gold is placed in hydrochloric acid, the acid will dissolve the gold and form a yellow solution.
Acid that Dissolves Platinum
The acid that dissolves platinum is hydrochloric acid.
Precipitation of Dissolved Platinum
- Dissolved platinum can be precipitated out of solution by adding a reducing agent, such as sodium bisulfite. The platinum will form a yellow precipitate, which can be collected by filtration.
- A piece of platinum will dissolve in aqua regia, a mixture of hydrochloric and nitric acids, to form platinum (IV) chloride, PtCl4.
- The platinum (IV) chloride will then precipitate out of the solution as a white solid when the solution is cooled below its freezing point.
Aqua Regia Handling
- Aqua Regia is a highly corrosive mixture of nitric acid and hydrochloric acid. It is used to dissolve gold and other precious metals. Aqua Regia must be handled with extreme caution. It can cause severe burns and blindness.
- Aqua Regia is a highly corrosive acid that is a mixture of nitric acid and hydrochloric acid. It is used to dissolve gold and other precious metals. Aqua Regia is very dangerous and must be handled with care.
- Aqua Regia is a highly corrosive acid that can cause severe burns to the skin and eyes. It can also cause respiratory problems if it is inhaled. Aqua Regia must be handled with extreme caution.
- Always wear protective clothing when handling Aqua Regia. This includes gloves, a lab coat, and goggles.
- Do not allow Aqua Regia to come into contact with your skin or eyes. If it does, flush the area with water for at least 15 minutes.
- If Aqua Regia is inhaled, move the person to fresh air and seek medical attention.
