Hydrogen chloride is a colorless non combustible gas. It is non-toxic and has a very pungent smell. Its specific gravity is greater than that of air. It produces white fog in case of humid air. It is very soluble in water and generates hydrochloric acid. It is highly corrosive, can react with a variety of metals to produce hydrogen, can form explosive mixture with air, and produce highly toxic hydrogen cyanide in case of cyanide.
Is hydrogen chloride a toxic gas?
Non toxic, hydrogen chloride is a colorless and pungent gas. Concentrated hydrochloric acid is a colorless liquid. When it is put in a bottle, white fog will be produced at the bottle mouth after a while (because hydrochloric acid is highly volatile, white fog is a small drop of hydrochloric acid produced by the combination of hydrogen chloride volatilization and water vapor in the air), which has a pungent and sour taste. However, in case of cyanide, it can produce highly toxic hydrogen cyanide gas.
Is hydrogen chloride a highly toxic chemical?
Hydrogen chloride is not a highly toxic chemical. The scientific name of hydrogen chloride is hydrochloric acid. The aqueous solution is commonly known as hydrochloric acid. It is very soluble in water. It is a colorless and non combustible gas with extremely irritating smell. It is white smoke in the air. At the same time, it is highly corrosive. It can react with a variety of metals to produce hydrogen and produce highly toxic hydrogen cyanide in case of cyanide.
Is hydrogen chloride a toxic and harmful gas?
It does not belong to toxic and harmful gases. Anhydrous hydrogen chloride is non corrosive, but it is highly corrosive in case of water. It can react with some active metal powders to release hydrogen. In case of cyanide, it can produce highly toxic hydrogen cyanide gas.
How harmful is hydrogen chloride?
Harm to the environment: it is harmful to the environment and can pollute the water body. Strong corrosivity in case of water
Fire and explosion hazard: This product does not burn and has strong irritation.
Harm to human health: hydrogen chloride has a strong stimulating effect on eyes and respiratory mucosa. Acute poisoning: headache, dizziness, nausea, eye pain, cough, blood in sputum, hoarseness, dyspnea, chest tightness, chest pain, etc. In severe cases, pneumonia, pulmonary edema and non expansion of the lung occur. Ulceration or opacity can be seen in the cornea. Direct skin contact can produce a large number of millet like red small papules and show flushing, pain and heat. Chronic effects: long term exposure to high concentrations can cause chronic bronchitis, gastrointestinal dysfunction and dental etching.
Harm of hydrogen chloride gas to people
In terms of harm to human body, hydrogen chloride has strong irritation to the upper respiratory tract and corrosive effect on eyes, skin and mucous membrane. Inhalation of hydrogen chloride causes rhinitis, laryngitis, bronchitis, pneumonia, headache, palpitation and suffocation. When swallowing, it will stimulate the mouth, throat, esophagus and stomach, causing salivation, nausea, vomiting, intestinal perforation, chills, fever, uneasiness, shock and nephritis. After inhaling hydrogen chloride, most of it is retained by the upper respiratory tract mucosa and neutralized in part, which can stimulate and burn the local mucosa and cause inflammatory edema, congestion and necrosis. Long term operation in an environment with a concentration of more than 15mg / m will cause chronic diseases such as tooth etching and chronic bronchitis. The symptoms caused by the local action of hydrogen chloride include conjunctivitis, corneal necrosis, damage to skin and mucosa, resulting in burns with severe pain. Long term exposure to low concentration hydrogen chloride can make the skin dry and earthy, and can also cause cough, headache, insomnia, dyspnea, hyperpalpitation, severe stomach pain and so on. The Z obvious symptom of chronic poisoning is that the tooth surface becomes rough, especially the front teeth produce spots.
