2NO + 3 H2O2 → 2HNO3 + 2H2O 2NO2 + H2O2 → 2HNO3 Concentrated nitric acid is also used to passivate equipment for use with hydrogen peroxide. While nitric acid and hydrogen peroxide are both hazardous chemicals, there are additional hazards that can arise when they are mixed together.
This study shows that, in vitro, nitric oxide reacts with hydrogen peroxide to release large amounts of chemiluminescence with the characteristics of the highly cytotoxic species, singlet oxygen.
The hydrochloric acid catalyzes an exothermic decomposition of hydrogen peroxide into oxygen and water. The accumulation of heat and non-condensable gas increases temperature and pressure in this reaction process always lead to runaway reaction and accident owing to inadvertent mixing.
Solutions made using hydrogen peroxide at concentrations greater than 50 wt % may cause an explosion. The 1:1 acid-peroxide mixtures will also create an explosion risk even when using common 30 wt. % hydrogen peroxide. Once the mixture has stabilized, it can be further heated to sustain its reactivity.
Never mix concentrated nitric acid and organics, such as acetone, unless you are following a respectable procedure and use a blast shield and proper precautions.
Hydrogen Peroxide (anhydrous) Chromium, copper, iron, most metals or their salts, aniline, any flammable liquids, combustible materials, nitromethane, and all other organic material. Hydrogen Sulfide Fuming nitric acid, oxidizing gases.
The brown fumes given off are quite harmful. Mixtures of nitric acid and alcohols higher than ethanol should not be stored. Mixtures of concentrated nitric and sulfuric acids are extremely dangerous, while strong mixtures of nitric acid and glycerin or glycols can be explosive.
Mix sulfuric acid with hydrogen peroxide in ratio 3:1 by volume. Measure 75 ml of sulfuric acid (H2SO4) and transfer to chemical glass. Add 25 ml hydrogen peroxide (H2O2) to the acid very slowlyto prevent overheat of the solution, never in reverse! 5.
The traditional piranha solution is a 3:1 mixture of sulfuric acid and 30% hydrogen peroxide. The solution may be mixed before application or directly applied to the material, applying the sulfuric acid, followed by the peroxide.
The world's strongest superacid is fluoroantimonic acid, HSbF6. It is formed by mixing hydrogen fluoride (HF) and antimony pentafluoride (SbF5). Various mixtures produce the superacid, but mixing equal ratios of the two acids produces the strongest superacid known to man.
The reaction of hydrogen peroxide on concentrated sulfuric acid produces highly activated and oxidizing peroxymonosulfuric acid (H2SO5), also called Caro's acid . Depending on the preparation procedure (see below), piranha solutions can contain up to 5% peroxymonosulfuric acid.
The boiling point of H 2O 2 has been extrapolated as being 150.2 °C (302.4 °F), approximately 50 °C (90 °F) higher than water. In practice, hydrogen peroxide will undergo potentially explosive thermal decomposition if heated to this temperature. It may be safely distilled at lower temperatures under reduced pressure.
Sulfuric acid reacts violently with alcohol and water to release heat. It reacts with most metals, particularly when diluted with water, to form flammable hydrogen gas, which may create an explosion hazard.
Chemiluminescence (CL) describes the emission of light that occurs as a result of certain chemical reactions that produce high amounts of energy lost in the form of photons when electronically excited product molecules relax to their stable ground state.
Chlorine gas is produced when sulfuric acid is mixed with chlorine bleach. This reaction is a function of the change in pH of the solution from alkaline to acidic combined with the strong oxidant properties of hypochlorous acid.
The principal method of manufacture of nitric acid is the catalytic oxidation of ammonia. In the method developed by the German chemist Wilhelm Ostwald in 1901, ammonia gas is successively oxidized to nitric oxide and nitrogen dioxide by air or oxygen in the presence of a platinum gauze catalyst.
Piranha solution is a strong oxidizer. Both liquid and vapour forms are extremely corrosive to skin and respiratory tract. Direct contact will create skin burns and will be extremely destructive to mucous membranes, upper respiratory tract and eyes.
Hydrogen peroxide is a good radical initiator, and thus should be quite effective at assisting in the decomposition of this pig/person. This mixture actually has a name: piranha solution. So, to answer, yes, a mixture of H2SO4 and H2O2 should do the job.
There is no acidic liquid that can even come close to changing the structure of those incredibly tightly packed carbon atoms. It just can't be done! So no, to put it plain and simple, acid can't melt diamonds.

❖ TNT is a yellow, odorless solid that does not occur naturally in the environment. It is made by combining toluene with a mixture of nitric and sulfuric acids (ATSDR 1995). ❖ It is a highly explosive, single-ring nitroaromatic compound that is a crystalline solid at room temperature (CRREL 2006).
Straight dynamite consists of nitroglycerine, sodium nitrate, and a combustible absorbent (such as wood pulp) wrapped in strong paper to make a cylindrical cartridge. Gelatin dynamite consists of a nitrocellulose-nitroglycerine gel.
Picric acid is used in the production of explosives, matches, and electric batteries. It is also used in etching copper and manufacturing colored glass, in the leather industry, and in the synthesis of dyes. Picric acid is very unstable and is a flammmable/combustible material.
