Watch this science video tutorial from Nurd Rage on how to make nitric acid. They show three ways to make nitric acid based on two different chemical approaches, both of which can be done using easily accessible materials. Warning: The procedures in this video produce large quantities of toxic gases and deal with highly corrosive acids. All work must be performed in a fume hood with proper ...
Dec 04, 2012· I want some nitric acid, around 70% or higher for a variety of experiments, involving making some aqua regia and some nitrocellulose. I have a distillation setup and all of the required chemicals to make nitric acid, but it is a lot of work with little yield. Are there any stores that sell OTC nitric acid.

Jul 19, 2017· The reaction among the two compounds is nearly explosive. Both of the compounds are highly oxidizing and the reaction is thus highly exothermic. When the acid is ready, the other main problem is the disposal of the acid as no base can easily neutralize such strong and harmful acid. Even it is the most dangerous acid of the world for human beings.
allows to choose the right refining process (Inquartation, direct Aqua Regia, electrolysis etc) to obtain the best results. 5) In case it is not possible to get the analysis of the metals contained in the alloy to be refined, it is advisable to indicate the possible carat content. Beside it is .

Solution for precipitating gold from HAuCl 4 solution. A discussion started in 2005 but continuing through 2018. 2005. Q. Respected Sir, My technical problem is how to precipitate gold from HAuCl 4 solution. We recover gold from Filings, Setting, Waste water, Consumables used in production, Emery papers, and sweeps from the production floors.
Nitric acid is commonly used to dissolve gold from printed circuits boards by making aqua regia, typically 1 part Nitric acid to 3 parts Hydrochloric acid. Molarity: Specific Gravity: This chemical ships only within the lower 48 US states using Standard Ground. HazMat fee applies. Adult signature required upon delivery.
Apr 29, 2006· Select ore samples suspected to contain GoldPlatinumPalladium and use concentrates equal to the size of one navy bean or pea. Place the concentrates in a clean test tube and add 1cc Nitric Acid and 3cc Hydrochloric Acid, (this a solution named Aqua Regia which is used regularly when testing.) Boil this over a lamp flame for about 5 to 8 minutes.

Aqua Regia is some nasty stuff. There likely wouldn't be a chest to find at this point if he did manage to find a lake of aqua regia to put it in. The only thing left would be the glass jar, any silver, any precious gems on the jewelry, and maybe a few scraps of wood from .

TCC's nitric acid belongs to the group of inorganic acids. It is both extremely corrosive and toxic. Consequently, direct contact can result in severe burns. Nitric acid is colorless when pure but has a yellowish appearance when it is old due to the collection of nitrogen oxides. Upon distillation, nitric acid in its pure form begins to boil at °C and becomes solid when it is well cooled.
The principle and equipment for Aqua Regia Aqua Regia has been used to separate gold from other metals for a long time. It is a kind of gold smelting flux like Borax, which is another chemical substance used in gold purification. Aqua Regia originates from a Latin word that means "royal water".
