Is perchloric acid Hazardous?

under some circumstances perchloric acid may act as an oxidizer and present an explosion hazards. Organic materials are especially susceptible to spontaneous combustion if mixed or contacted with perchloric acid. Under some circumstances, perchloric acid vapors form perchlorates in ductwork, which are shock sensitive.

What happens when you touch perchloric acid?

At room temperature, perchloric acid up to concentrations of 72\% has properties similar to other strong mineral acids. It is a highly corrosive substance and causes severe burns on contact with the eyes, skin, and mucous membranes. When used under these conditions, perchloric acid reacts as a strong non-oxidizing acid.

What are some hazards of acids?

1 Hazards of Acids. Acids are proton donors. They are corrosive to eyes, skin, and mucous membranes. Acid corrosion or burning of tissue is a function of both the pH and the capacity of the particular anions to combine with protein.

What does perchloric acid do to blood?

Perchloric acid is commonly used to denature and precipitate proteins in samples before various metabolites are measured in tissue, blood, and other body fluids. However, perchloric acid can interfere in the analytical process, possibly by inhibiting the enzymes used.

Can perchloric acid explode?

Note: Anhydrous perchloric acid is extremely unstable and will explode on contact with organic material (or spontaneously on storage). Care should be taken to ensure perchloric acid is not mixed with dehydrating agents to avoid producing it.

How are acids and bases harmful?

Acids and bases are corrosive substances that can attack various surfaces including human tissue. The amount of tissue damage they cause depends on the strength and concentration of the acid or base and the duration of exposure. The acidity or alkalinity of a substance can be determined by its pH value.

What does perchloric acid smell like?

no odor
Perchloric acid is a strong mineral acid commonly used as a laboratory reagent. It is a clear, colorless liquid with no odor.

Why is perchloric acid explosive?

Perchloric acid forms an azeotrope with water at a concentration of 72.5\% perchloric acid. At elevated temperatures, vapors from perchloric acid can condense on surfaces in the ductwork of the hood, where they form perchlorate salts that are often highly shock-sensitive and that pose a serious explosion hazard.

What happens if you eat perchloric acid?

Ingestion of perchloric acid will cause mouth, throat, stomach and intestinal tract burns, along with abdominal pain and diarrhea. Perchlorate salts are a class of potentially explosive chemicals that contain the perchlorate anion (ClO4-).

Are perchlorate salts harmful to humans?

Perchlorate salts may be harmful if ingested, inhaled, or absorbed through the skin. These compounds may cause irritation to the gastrointestinal tract, respiratory tract, skin, and eyes. Some perchlorate salts are mass explosion hazards. Additionally, upon combustion it forms hazardous products such as nitrogen oxides and hydrogen chloride gas.

How should I handle and store perchloric acid and perchlorate salts?

All handling and use of perchloric acid and perchlorate salts must be performed inside a certified chemical fume hood and with the sash at the lowest possible height for safe usage of reagents.

What is perchloric acid and its properties?

Perchloric acid is a chlorine oxoacid. It is a conjugate acid of a perchlorate. Perchloric acid, with more than 50\% but not more than 72\% acid appears as a clear colorless odorless aqueous solution. Corrosive to metals and tissue. Closed containers may rupture violently under prolonged exposure to heat.
