2. Piranha solution - Wikipedia

   en.wikipedia.org/wiki/Piranha_solution

   Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2). The resulting mixture is used to clean organic residues off substrates, for example ...

3. Sulfuric acid - Wikipedia

   en.wikipedia.org/wiki/Sulfuric_acid

   Sulfuric acid is a very important commodity chemical; a country's sulfuric acid production is a good indicator of its industrial strength. [9] Many methods for its production are known, including the contact process, the wet sulfuric acid process, and the lead chamber process. [10] Sulfuric acid is also a key substance in the chemical industry.

4. Green death - Wikipedia

   en.wikipedia.org/wiki/Green_death

   Green death is a solution used to test the resistance of metals and alloys to corrosion. It consists of a mixture of sulfuric acid, hydrochloric acid, iron(III) chloride and copper(II) chloride and its boiling point is at approximately 103 °C. Its typical chemical composition is given in the table hereafter: [1] [2] [3] [4]

5. Oleum - Wikipedia

   en.wikipedia.org/wiki/Oleum

   Oleum (Latin oleum, meaning oil), or fuming sulfuric acid, is a term referring to solutions of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid (also known as pyrosulfuric acid). [1] Oleums can be described by the formula ySO 3 ·H 2 O where y is the total molar mass of sulfur trioxide ...

6. Pickling (metal) - Wikipedia

   en.wikipedia.org/wiki/Pickling_(metal)

   Strong acids, such as hydrochloric acid and sulfuric acid are common, but different applications use various other acids. Also alkaline solutions can be used for cleaning metal surfaces. Solutions usually also contain additives such as wetting agents and corrosion inhibitors. Pickling is sometimes called acid cleaning if descaling is not needed ...

7. Aqua regia - Wikipedia

   en.wikipedia.org/wiki/Aqua_regia

   The hydrochloric acid provides a ready supply of chloride ions (Cl −), which react with the gold ions to produce tetrachloroaurate(III) anions ([AuCl 4] −), also in solution. The reaction with hydrochloric acid is an equilibrium reaction that favors formation of tetrachloroaurate(III) anions.

   Many people have a significant imbalance of omega-6 to omega-3 in their bodies — a November 2015 study found levels of linoleic acid have increased by 136% in the fat tissue of Americans over ...

9. Chemical burn - Wikipedia

   en.wikipedia.org/wiki/Chemical_burn

   Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the ...
