What is the difference between red fuming and white fuming nitric acid?
Red fuming nitric acid contains nitrogen dioxide, giving it a reddish-brown color, while white fuming nitric acid does not. White fuming nitric acid is purer and more concentrated than red fuming nitric acid. Both are strong oxidizing agents used in various industrial processes.
How do you prepare fuming nitric acid from nitric acid 69 percent?
To prepare fuming nitric acid from 69% nitric acid, you would need to concentrate the nitric acid by distillation under vacuum or by adding a dehydrating agent like concentrated sulfuric acid. This process will remove water and some nitrogen dioxide, resulting in fuming nitric acid with a higher concentration of nitric acid. Ensure to follow proper safety procedures due to the hazardous nature of fuming nitric acid.
Why add the nitric acid?
Nitric acid (HNO3), also known as aqua fortis and spirit of nitre, is a highly corrosive and toxic strong mineral acid which is normally colorless but tends to acquire a yellow cast due to the accumulation of oxides of nitrogen if long-stored. Ordinary nitric acid has a concentration of 68%. When the solution contains more than 86% of it, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as white fuming nitric acid or red fuming nitric acid, at concentrations above 95%. Nitric acid is also commonly used as a strong oxidizing agent.
What are the subsidiary hazards for Nitric Acid Red Fuming?
The main subsidiary hazards for Nitric Acid Red Fuming include toxicity, corrosion, and potential for combustion when in contact with organic materials. It can also react violently with other substances, causing explosions and releasing toxic gases. Proper handling, storage, and disposal procedures are crucial to prevent accidents and exposure.
Why is nitric acid kept in air tight reagent bottle?
Nitric acid is highly corrosive and can react with moisture in the air, forming nitrogen dioxide gas. Storing it in an airtight container helps prevent these reactions and ensures the acid remains at its desired concentration and potency.
What is fuming nitric acid price?
The Price of Fuming Nitric Acid ! Marutifinechemicals Fuming nitric acid is one of the most popular forms of nitric acid. The price of fuming nitric acid for marutifinechemicals is based on the weight of the acid and its purity. The price is also dependent on how much you need, which can be calculated by multiplying the amount bought by the cost per pound.

Red fuming nitric acid contains nitrogen dioxide, giving it a reddish-brown color, while white fuming nitric acid does not. White fuming nitric acid is purer and more concentrated than red fuming nitric acid. Both are strong oxidizing agents used in various industrial processes.
What makes nitric acid fuming?
Fuming nitric acid is the term used when the solution contains more than 86% HNO3. The characterization of fuming nitric acid varies based on the concentration of nitrogen dioxide. Concentrations above 86% are classified as red fuming nitric acid, while concentrations above 95% are known as white fuming nitric acid.

How to convert aniline to picric acid?
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
Why does pure nitric acid fume in moist air?
Pure nitric acid fumes in moist air because it absorbs water from the air, forming a mist of nitric acid droplets. These droplets reflect light, giving the appearance of fuming. Nitric acid is highly hygroscopic, meaning it has a strong tendency to attract and hold onto water molecules from the surroundings.
What is the source of nitric acid?
Nitric acid is typically produced by the oxidation of ammonia with air in the presence of a catalyst at high temperatures. This process creates nitrogen dioxide, which is then dissolved in water to form nitric acid. Additionally, nitric acid can also be produced by the reaction of nitrogen oxides with water.
What is an example of strong acid?
The strongest of acids are called fuming acids or anhydrous acids. Fuming nitric and fuming sulfuric acids are so strong that adding water to them converts them to nitric and sulfuric acids generating a very great amount of heat. Anhydrous acetic acid is likewise so strong that adding water will convert it to 100% acetic acid. These 3 acids are used in special reactions in chemistry where only the strongest acids will do.
How do you prepare 2N nitric acid?
It's not exactly the sort of thing you can do in your kitchen, if that's what you were hoping for. Industrially it's made by heating air to very high temperatures to roast the nitrogen into NO2, then reacting that with water to produce nitric acid.
