RECOVERY AND REFINING WITH JUST NITRIC ACID

how can you refine with just nitric acid? the answer is simple nitric acid or our nitric substitute acid will desolve all metals except for gold some platinum group metals (platinum rhodium etc) may not desolve this is not an issue because if you sort your materials properly you will not have any platinum group metals in the mix Neutralizing nitric acid with sodium bicarbonateNeutralizing nitric acid with sodium bicarbonate I want to neutralize 100 gallons of 5% nitric acid and water solution with sodium bicarbonate how much sodium bicarbonate would I need?

Nitric acid

A solution of nitric acid water and alcohol Nital is used for etching metals to reveal the microstructure ISO 14104 is one of the standards detailing this well known procedure Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications Nitric acid substitute The world's most popular metal finishing site and striving to be the internet's friendliest corner topic 460 Nitric acid substitute 2000 Q I'm looking for a chemical substitute for our nitric acid mixture bath used for chemical deburring of non-ferrous alloy electronic pin connector parts how to make subzero solution nitric acid substitutesubzero nitric acid substitute SubZero is a powdered nitric acid substitute to which HCl is added to make substitute aqua regia = But if a reader wants CBX for some purpose for which aqua MORE refiningrecovery and refining with just nitric acid substitute How to prepare 0 1N nitric acid from fuming nitric acid Best Answer Fuming nitric acid is so variable in strength that you MUST do this in two stages 1] Fuming nitric acid is approximately 24 moles per L If you dilute it 24 times you should get approx 1 N solution and 240 times will give approximately 0 1N Aqua Regia Refining Instructions To the container add 30 milliliter of nitric acid (or 2 tablespoons subzero nitric acid substitute) for every ounce of metal in the container So if you have 10 ounces of metal in the container add 300 ml (milliliter) of nitric acid Let it sit about 30 minutes or longer You may or may not get a strong reaction with brown fumes

Alternative to Nitric acid /research

Alternative to Nitric acid /research Many time i wanted to disolve metals like copper nickel without very high suscess because i dont have nitric acid and nitrate salt is not disponible to me So I desided to find an cheap alternative altoug i need to make more work to get an high yield product Nitric Acid Suppliers AustraliaNitric acid solution 2 mol/l (2 N) Size 1 Litres Brand Scharlau Code AC POCD Scientific suppliers of Reagents Chemicals in Australia NSW ALUMINIUM AAS STANDARD SOLN 1000 PPM LR (NITRIC ACID MATRIX)(nitric acid matrix) Quick enquiry Where to buy Suppliers range NSW Nitric acid Some 99% acid is required for the manufacture of for example organic nitro-compounds for the explosives and dye industries Nitric acid and water form an azeotropic mixture with a maximum boiling point of 395 K containing ca 68% nitric acid by mass thus the concentrated acid cannot be obtained by distillation of the aqueous solution
