What chemicals do I need to extract gold from electronics
Place your world boards in a glass jar. In another container, mix two parts of hydrochloric acid and one part of weak hydrogen peroxide (three percent concentration). Pour this mixture over these circuit boards so that they are just submerged in water.

Can nitric acid extract gold
Regia water, known for its corrosiveness, consists of a mixture of nitric and hydrochloric acids, which in the right proportion can liquefy non-reactive elements such as gold and therefore platinum. While it can be used to mine gold, aqua regia has a number of disadvantages.
Can nitric acid alone dissolve gold
So gold is a very, very less reactive metal. We know that the strongest acids, such as hydrochloric, uric, and nitric acids, are incapable of dissolving gold by themselves. This is because gold, one of the most reactive metals, cannot replace the hydrogen of these acids because it is actually less reactive than true hydrogen.
What is the easiest way to get gold out of electronics
An alternative to the Canadian researchers is a solution of acetic acid and a fine oxidizing agent – a non-toxic method if you want to dissolve the gold, which initially exits the circuit in about 10 seconds and exits nickel, copper, iron and various metals in circuit boards.
When glucose is heated with nitric acid the product is a lactic acid B saccharic acid C Glycollic acid D oxalic acid
Answer: 2) Sweet stomach acid. Explanation: Glucose is oxidized by acidic nitric acid and produces a sweet acidity.
Which of the following is a diprotic acid * hydrochloric acid Sulphuric acid phosphoric acid nitric acid
The correct answer is almost certainly d) sulfuric acid. (a) Phosphoric acid: Phosphoric acid is a triprotonic acid.
What is the difference between nitric acid and fuming nitric acid
The main difference between fuming nitric acid and concentrated nitric acid is that fuming nitric acid produces colorless, yellowish, or brownish smoke, unlike concentrated nitric acid, which does not normally produce smoke; But if you’re just very concentrated, this product can produce clouds of creamy white smoke.
What is the difference between concentrated nitric acid and fuming nitric acid
The main difference between, for example, fuming nitric acid and pure nitric acid is that fuming nitric acid produces a colorless, yellowish to brownish smoke, while condensed nitric acid does not normally produce much smoke; but the very high flash point of this acid can produce off-white fumes.
Will the nitric acid in the wash water interfere with the weight of the silver chloride ?( Nitric acid is prepared by dissolving the gas n2o5 in water
Nitric acid will not interfere with your analysis to find a lot of silver in the metal. … When NaCl is added, silver ions combine with chloride ions to form a new AgCl(s) precipitate, which is filtered and washed.
Which acid is weaker than benzoic acid p nitrobenzoic acid p methylbenzoic acid p chlorobenzoic acid chlorobenzoic acid
Answer: Acetic acid is weaker than benzoic acid because some of the linked methyl groups in acetic acid give the electron density to COO? the addition of which destabilizes the anion. So Fix C.
Can nitric acid extract gold
To purify gold with nitric acid, you must first purify nitric acid with hydrochloric acid to create Regia Aqua. Then it must be dissolved, filtered to remove gold from the substances to which it is attached. … get rid of acids only after getting rid of them before.
What happens when benzoic acid is treated with concentrated nitric acid in the presence of concentrated Sulphuric acid
H2SO4? m-Nitrobenzoic acid is usually formed by mixing benzoic acid with a treated mixture of conc. HNO3 and conc.
Which of the following is Tetrabasic acid a orthophosphoric acid hypophosphorous acid Metaphosphoric acid pyrophosphoric acid
Acid) (Pyrophosphoric acid is a tetrabasic acid; it releases only four H+ ions.
