What is fuming nitric acid?
a colorless, yellowish, or brownish fuming corrosive liquid, usually prepared from nitric acid by the addition of excess nitrogen dioxide: used in organic synthesis for nitration, and as an oxidizer in liquid propellants for rockets.
What is ACS grade nitric acid?
ACS grade Nitric Acid is material of a higher quality, commonly also described as “Reagent” material. It is used across many industries for a wide variety of production processes, and commonly required by laboratories.
What molarity is fuming nitric acid?
21.4 M.
Commercial-grade fuming nitric acid contains 98% HNO3 and has a density of 1.50 g/cm3. This grade is often used in the explosives industry. It is not as volatile nor as corrosive as the anhydrous acid and has the approximate concentration of 21.4 M.
What is the difference between concentrated nitric acid and fuming nitric acid?
The key difference between fuming nitric acid and concentrated nitric acid is that the fuming nitric acid forms a colorless, yellowish or brownish fume whereas the concentrated nitric acid usually does not form a fume; but a very high concentration of this acid may give off-white colored fumes.
Why is fuming nitric acid used?
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of 84% nitric acid (HNO3), 13% dinitrogen tetroxide and 1–2% water. RFNA increases the flammability of combustible materials and is highly exothermic when reacting with water.
How do you make nitric acid stronger?
The simplist and most used preparation of nitric acid in the lab is by adding concentrated sulfuric acid to a dry nitrate salt, usually, potassium or sodium nitrate. This mixture is heated to melt the pasty mixture and distill the nitric acid.
What is another name for nitric acid?
Nitric acid (HNO3), also known as aqua fortis (Latin for “strong water”) and spirit of niter, is a highly corrosive mineral acid.
What is the molarity of 70 nitric acid?
Dilutions to Make a 1 Molar Solution
| Concentrated Reagents | Density | Molarity (M) |
|---|---|---|
| Nitric acid 70% | 1.42 | 15.8 |
| Perchloric acid 60% | 1.54 | 9.2 |
| Perchloric acid 70% | 1.67 | 11.6 |
| Orthophosphoric acid 85% | 1.7 | 15.2 |
Does nitric acid dissolve gold?
Aqua regia is a mixture of nitric and hydrochloric acids. It takes its name from its ability to dissolve gold, which is sometimes referred to as the royal metal. As seen in the first equation, a gold alloy of 14 K or lower will dissolve when nitric acid is added.
What is the pH of nitric acid?
1.2
Nitric acid (HNO3) has a pH level of 1.2 at standard commercial concentration of 68%.
What is pH of nitric acid?
3.01
pH of Common Acids and Bases
| Acid | Name | 1 mM |
|---|---|---|
| HNO3 | nitric acid | 3.01 |
| H3PO4 | orthophosphoric acid | 3.06 |
| H3AsO4 | arsenic acid | 3.08 |
| H2SeO3 | selenous acid | 3.15 |
How big are the converters for nitric acid?
Three ammonia converters installed in a modern nitric acid plant operated by Imperial Chemical Industries Limited. Each converter has three rhodium-platinum catalyst gauzes, 114 inches in diameter, woven by Johnson Matthey & Co Limited.
How does De Dietrich process system treat nitric acid?
For the recovery, the cleaning respectively the so called denitration and further purification of nitric acid from various waste and feed streams De Dietrich Process Systems has developed optimum processes and realized numerous plants worldwide.
What is the density of white fuming nitric acid?
One specification for white fuming nitric acid is that it has a maximum of 2% water and a maximum of 0.5% dissolved NO. 2. . Anhydrous nitric acid has a density of 1.513 g/mL and has the approximate concentration of 24 molar.
What are the steps in making nitric acid?
The modern nitric acid process proceeds essentially in three stages: Liquefied ammonia is vapourised and pre-heated before being mixed with preheated air. The mixture at about 300°C, and usually containing 10.5 to 12 volume per cent of ammonia, is passed downwards through a pad of platinum alloy gauzes in a converter.
