A corrosive, fuming, volatile mixture of hydrochloric and nitric acids, used for testing metals and dissolving platinum and gold. Also called nitrohydrochloric acid. - This will make 3 Litres of Aqua Regia (enough supply to last for months.
Please see more info tab on instructions for mixing.
**PLEASE NOTE: - YOU MUST BE 18 YEARS OR OLDER BEFORE YOU CAN PURCHASE ANY ACID***
Aqua Regia - Hydrochloric Acid & Nitric Acid Combo
1. Ensure that both acids are chilled.
2. Use chemical resistant glass only. NO METAL OBJECT
3. Mix 9 parts of nitric acid to 41 parts of hydrochloric acid
( Just pour 50 ml of HCl (hydrochloric Acid) into 11ml HNO3) (Nitric Acid)
Pour HCl into HNO3 slowly but steadily. Use fume cap or make it in a open space!
Aqua regia decays after being mixed up, so you always have to make it fresh. The nitric acid slowly works on the chloride ion, generating chlorine gas, leading to a pleasant swimming-pool aroma if you just catch a whiff, or choking fumes if you get more than that (Caution: Chlorine is really a violent poison if inhaled).
Also generated is the toxic nitrosyl chloride (NOCl), which is a beautiful reddish-orange. So you mix concentrated nitric acid (colorless, or maybe tinted just barely yellow, but mostly clear), concentrated hydrochloric acid (colorless), and you get a red-orange, bubbling, smelly solution that can dissolve gold.
Please ensure that you do this in a well vented space, and wear all safety equipment.
