Piranha solutions is a mixture of concentrated sulfuric acid (H2SO4) and 30% hydrogen peroxide (H2O2). Sulfuric Acid. Signal word: Danger Hazard statement(s): H290 May be corrosive to metals. H314 Causes severe skin burns and eye damage. Hydrogen Peroxide. Signal word: Danger Hazard statement(s): H271 May cause fire or explosion; strong oxidizer.
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).

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.
In case of skin contact: Flush the skin with copious amounts of water for at least 15 minutes. Seek medical attention. In case of eye contact: Utilize eyewash station immediately to flush contaminated eye(s) for at least 15 minutes. Seek medical attention. In case of inhalation: Conscious persons should be assisted to fresh air. Seek medical attent...
Always use glass (Pyrex® is preferred) containers. The solution can degrade plastic containers causing failure of containment.Ensure all containers are properly labeled to identify those containing piranha acid solutions.Always mix the solution in the hood, utilizing the hood sash as a barrier between you and the solution.

DO NOT add sulfuric acid to hydrogen peroxide.Introduction. "Piranha solution” is a substance that is used to remove organic residues from substrates. There are two different solutions that are used: Acid Piranha (most common): is a 3:1 mixture of concentrated sulfuric acid (H2SO4) with hydrogen peroxide (H2O2). Base Piranha (least common): is a 3:1 mixture of ammonium hydroxide (NH4OH ...

Piranha solution, also known as piranha etch, is a strong oxidizing agent that removes most organic matter. It will also hydroxylate most surfaces by adding hydroxyl ( -OH) groups, rendering them highly hydrophilic (water compatible). Piranha solutions are often used to clean organic residues off substrates.
