Piranha solution, also known as piranha etch, is a mixture of sulfuric acid ( H2SO4) and hydrogen peroxide ( H2O2 ). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [1] .
Oct 7, 2014 · In this video we make and demonstrate the oxidizing power of piranha solution. Piranha solution is a 3:1 mixture of sulfuric acid to hydrogen peroxide. NOTE: I used nitrile gloves in this...
May 4, 2020 · Piranha solution gets its name for its aggressive attack of organic material, like a school of piranha in a feeding frenzy. Piranha solution is an aqueous mixture of sulfuric acid (H 2 SO 4 ) and hydrogen peroxide (H 2 O 2 ) that removes organic residue from surfaces and makes them more hydrophilic.

Jun 4, 2020 · Chemical piranha solution or piranha etch is a mixture of a strong acid or base with peroxide, mainly used to remove organic residue from glass and other surfaces. It's a useful solution, but hazardous to make, use, and dispose of, so if you need to prepare this chemical, read over the precautions and disposal advice before you get started.
Overview. Piranha solutions are used to remove organic residues from substrates, particularly in microfabrication labs. 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.
Dec 29, 2021 · Piranha solution is a dangerous and useful substance used throughout academia and industry. However, there is little peer-reviewed work on its safe use, and institutional protocols are limited in their applicability beyond their institute of origin.

Piranha solutions are strong oxidizers used to remove organic residues from substrates. As such, piranha solutions are extremely corrosive, reactive, and potentially explosive. Most commonly used is the acid piranha, typically a 3:1 Sulfuric Acid (H2SO4) and Hydrogen Peroxide (H2O2).
Sep 4, 2019 · Piranha solution (also known as piranha etch or acid piranha) is a popular name for a solution of Caro's acid [1] which is usually prepared by reacting sulfuric acid and hydrogen peroxide; it is used to clean organic residues from glassware or other acid resistant materials.
