Product Description

 Hello everyone! We are Chongqing Yuhan Technology. We have been deeply involved in the chemical industry for many years and specialize in the trade of chemical raw materials. We have a wide business scope and rich resources, especially in the supply of chemical raw materials related to gold refining. In the process of gold refining, a variety of chemical raw materials play a key role, and we happen to have a rich product line. For example, sodium cyanide is an important raw material for traditional cyanidation gold extraction. With mature technology and high gold extraction efficiency, it is widely used in large-scale gold mining. We can provide sodium cyanide products with stable quality and meet relevant standards. 
 

Introduction

Aqua regia is a yellow - orange fuming liquid with a pungent and irritating odor. It is renowned for its remarkable ability to dissolve noble metals like gold and platinum, which are otherwise resistant to most common chemical reagents. This property has made it an important reagent in various fields, including metallurgy, analytical chemistry, and the processing of precious metals.

Composition and Ratio

The typical composition of aqua regia is a mixture of nitric acid and hydrochloric acid in a volume ratio of approximately 1:3. That is, for every one part of nitric acid, there are three parts of hydrochloric acid. This specific ratio is crucial for achieving the unique chemical properties of aqua regia. The nitric acid acts as a strong oxidizing agent, while the hydrochloric acid provides chloride ions that can form stable complexes with the metal ions produced during the oxidation process.

Preparation

To prepare aqua regia, it is necessary to handle the acids with extreme caution due to their corrosive and toxic nature. Usually, the hydrochloric acid is poured into a container first, and then the nitric acid is slowly added to it while stirring gently. The mixing process should be carried out in a well - ventilated fume hood to avoid inhaling the toxic fumes released during the reaction. It is important to note that the reaction between the two acids is exothermic, meaning it releases heat, so the addition should be done slowly to prevent excessive heating and potential splashing of the mixture.

Applications

• Metal Dissolution: As mentioned earlier, its primary use is in dissolving noble metals. In the jewelry industry, it can be used to refine gold and platinum. In metallurgical research, it helps in analyzing the composition of alloys containing these metals.
• Chemical Etching: It is used in the semiconductor industry for etching metal - based components on microchips. The precise control of the etching process using aqua regia helps in creating the desired patterns and structures on the semiconductor wafers.
• Analytical Chemistry: In analytical laboratories, aqua regia is used to digest samples containing metals. This allows for the subsequent analysis of the metal content using techniques such as atomic absorption spectroscopy or inductively coupled plasma - mass spectrometry.
