How to extract gold without using any harmful acids like aqua regia? The traditional aqua regia (mixture of Hydrochloric and nitric Nitric acid Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% i… en.wikipedia.org acids in the proportion of 3:1 volume ratio, respectively) method is used to refine pure gold (24Karat = 99.99% purity) from factory scrap.

Which of the following is Tetrabasic acid a orthophosphoric acid hypophosphorous acid Metaphosphoric acid pyrophosphoric acid
(pyrophosphoric acid) was a tetrabasic acid because it donates four H+ ions.
When glucose is heated with nitric acid the product is a lactic acid B saccharic acid C Glycollic acid D oxalic acid
Answer: 2) Sugar acid. Explanation: Glucose is oxidized with nitric acid to form carbohydrate acid.
Which of the following is a diprotic acid * hydrochloric acid Sulphuric acid phosphoric acid nitric acid
The correct way is d) sulfuric acid. (a) Phosphoric acid: Phosphoric acid is a true triprotonic acid.
How do you refine gold with acid
Add 120 milliliters of hydrochloric acid for every ounce of gold in the container. For 5 ounces indicating gold, that would be just 600 milliliters of HCL. When hydrochloric acid is added, the mixture turns brown and smoke may form. Depending on how the chemicals react and heat up, the type of gold will dissolve.
