What is the function of the sulfuric acid in the nitrating mixture?

Sulfuric acid is needed in order for a good electrophile to form. Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur.

How do you remove sulfuric acid from air?

Several methods have been proposed to remove air pollutants, such as sulfuric acid, from air stream [4], [7]. Absorbers and mist control devices such as electrostatic precipitators and fiber mist eliminators can be used to remove sulfuric acid mists [8].

What will sulfuric acid eat through?

Reactivity. Sulfuric acid is very reactive and dissolves most metals, it is a concentrated acid that oxidizes, dehydrates, or sulfonates most organic compounds, often causes charring. Sulfuric acid reacts violently with alcohol and water to release heat.

How aniline is nitrated?

In case of nitration in aniline, the Nitric Acid protonates the aniline to form the Anilinium ion. Now since the nitrogen atom has no lone pair to conjugate, it has no mesomeric effect on the ring, the but as nitrogen is now protonated, it has a high negative inductive effect.

Why nitrating mixture is used in nitration?

It helps to eliminate some of the delocalized electrons from the benzene ring because it has no lone pairs to donate and has electronegative atoms, making it less vulnerable to electrophilic attack. The nitration of nitrobenzene produces three products.

What happens if you touch sulfuric acid?

If you touch sulfuric acid, it will burn your skin. If you get sulfuric acid in your eyes, it will burn your eyes and cause them to water. The term “burn” used in these sections refers to a chemical burn, not a physical burn resulting from contacting a hot object.

What happens when Sulphuric acid is mixed with water?

Sulfuric acid (H2SO4) reacts very vigorously with water in a highly exothermic reaction. If you add water to concentrated sulfuric acid, it can boil and spit and you may get a nasty acid burn.

How do you make a concentrated sulfuric acid dilute?

Fortunately, such a process exists and is relatively simple to perform. One can concentrate Sulfuric acid by heating the liquid and boiling off water from the solution, leaving concentrated H2SO4 behind. By following this procedure, Sulfuric acid solutions may be concentrated to upwards of 98\% H2SO4 by weight.
