What is the hazard rating for hydrochloric acid?
7647-01-0
Single Target Organ (STOT): 7647-01-0: The substance or mixture is classified as specific target organ toxicant, single exposure, category 3 with respiratory tract irritation.
Is HCL a hazardous chemical?
Hydrochloric acid is a hazardous liquid which must be used with care. The acid itself is corrosive, and concentrated forms release acidic mists that are also dangerous. If the acid or mist come into contact with the skin, eyes, or internal organs, the damage can be irreversible or even fatal in severe cases.
Is hydrochloric acid considered stable according to the NFPA hazard label?
Chemical stability:Stable under normal conditions. Possible hazardous reactions: Conditions to avoid:Incompatible materials.
What is MSDS of HCL?
Inhalation: Vapors and mist will irritate throat and respiratory system and cause coughing. Skin contact: Causes skin burns. Eye contact: Causes eye burns. Ingestion: Harmful if swallowed.
Is HCl organic or inorganic?
Commonly used inorganic acids are sulfuric acid (H2SO4), hydrochloric acid (HCl), and nitric acid (HNO3). Inorganic acids range from superacids (such as perchloric acid, HClO4) to very weak acids (such as boric acid, H3BO3). Inorganic acids tend to be very soluble in water and insoluble in organic solvents.
How do you handle HCl?
Handling. Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood.
What is hydrochloric acid used for?
Hydrochloric acid (HCl) is commonly used for the neutralization of alkaline agents, as a bleaching agent, in food, textile, metal, and rubber industries. It is neutralized if released into the soil and it rapidly hydrolyzes when exposed to water.
Is HCl unstable?
Normally stable but can become unstable at elevated temperatures and pressures.
Is hydrochloric acid stable?
Hydrochloric acid is classified as a stable molecule. When stored, HCl is considered to last indefinitely without denaturing, decomposing, or losing its strength and chemical properties when stored by itself.
Why HCl is not organic acid?
Explanation: Hydrochloric acid is a necessary acid in body, especially in our stomach. It helps kill bacteria and viruses prevent us from infection. Hydrochloric acid does not consider as organic acid because of the absence of carbon in it.
What is the pH for HCl?
1.5 to 3.5
Hydrochloric acid is an essential component of gastric acid, which has a normal pH of 1.5 to 3.5. A weak acid or base does not ionize completely in aqueous solution. Ionization of a weak acid (HA) is characterized by its dissociation constant (Ka).
Can I pour hydrochloric acid down the drain?
Never dispose of hydrochloric acids or any other acids or bases on the ground, in a storm drain or in a gutter, because they can contaminate groundwater, surface water and drinking water supplies.
What is the NFPA hazard rating system?
The hazard rating system they designed is called the NFPA 704 Diamond , and it classifies chemicals numerically from 0 to 4 based off of four attributes. The higher the number, the more dangerous the chemical in that category. The four categories that are used for analyzation are health, reactivity, flammability, and special hazards.
What are the hazards of HCl?
Hazards of HCl, or hydrochloric acid, include both acute and chronic effects. Acute effects include corrosion to the eyes, skin and mucous membranes as well as pulmonary and upper respiratory irritation. Chronic effects include gastritis, bronchitis and dermatitis among those frequently exposed to the substance.
What are the dangers of hydrochloric acid?
Hydrochloric acid is a toxic chemical with a variety of household and industrial uses. Inhalation of vapors can cause burns to all body tissues, lung damage and even death in extreme cases. A common household use for hydrochloric acid is cleaning concrete or masonry to prepare it for painting or sealing.
What are the NFPA ratings?
The National Fire Association (NFPA) hazard rating is a rating system for all chemicals and hazardous materials. The system uses a symbol on the container that has a combination of four colored diamond arrays within a bigger diamond shape.
