2023年11月21日 · Nitric acid is a strong acidic compound, with the chemical formula HNO 3. The nitric acid molecule consists of a nitrogen atom bonded to a hydroxyl group (OH) and two oxygen molecules. A double ...

2018年1月12日 · De-NOxing your acid. Yellow azeotropic nitric acid can be turned white, or RFNA converted to WFNA, by using oxygen. Oxygen oxidizes NO 2 to N 2 O 5, which combines with the residual water in your acid to produce nearly pure nitric acid. Oxygen can be introduced with two methods. One is directly bubbling oxygen gas through your acid.

2023年9月23日 · Nitric acid in general reacts with rubber; do not try to distill it in apparata that contain rubber parts. Use ground glass joints or a retort when distilling nitric acid, especially of fuming concentration. Storage. Nitric acid is incompatible with most plastics due to its oxidizing nature, though bottle lids made of polypropylene (PP) are ...

2012年12月4日 · Where can I buy Over The Counter Nitric Acid? 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 ...

2024年12月25日 · The sulfuric acid is in a 1:2 ratio with the nitric acid product so the one half the molar mass is required: 1.745mol / 2 = 0.8725 mol sulfuric acid required. So,: (0.8725mol)(98.079g/mol) = 85.57g sulfuric acid

2024年6月9日 · Nitric acid from calcium nitrate I normally produce nitric acid from magnesium nitrate and sodium bisulfate dry distillation and it works great. I have however allot of calcium nitrate I want to use but the Nurdrage procedure for the distillation of this with sodium bisulfate works great but erodes chunks of glass from my flasks and breaks them!

2007年6月10日 · nitric acid from calcium nitrate I recently acquired 50 pounds of calcium nitrate fertilizer. Later to my annoyance i found out it was actually a calcium nitrate ammonium nitrate double salt. But that's the a big problem, theres only ~7.5% ammonium nitrate, I just dissolve it along with CaOH and boil off the NH3.

2013年10月9日 · Concentrating Nitric acid Hi, Because i need a high nitric acid concentration, preferbly over 95%, for something, I want to know how to concentrate the acid in easiest way. First, I made my nitric acid by blowing NO2 gas bubbles into cold water. For around half an hour until the color becomes yellow, so i guess it has at least around 10% ?

2014年8月10日 · when one deals with nitric acid. The product of the reaction with diluted nitric acid is, again, a gas (depending on the quantity of the added Cu2+ ions the reaction may be somewhat vigorous). In all instances but one, where a minor puff occurred, the product gas was nonflammable, thus suggesting that hydrogen is far from being the principal

Ammonia and nitric acid b. sodium acetate(NaC_2 H_3 O_2) and hydrochloric acid Give the balanced chemical equation for the reaction of ammonia with water to form ammonium hydroxide. Write a balanced equation to represent the decomposition of solid ammonium nitrate into dinitrogen monoxide gas and liquid water.
