What are the physical and chemical properties of cyanide?
Hydrogen cyanide (AC) is a pale blue or colorless liquid below 78° F and a colorless gas at higher temperatures. It has a bitter almond odor and is highly volatile and flammable at room temperature. Sodium cyanide and potassium cyanide are white powders which may have a bitter almond-like odor.
What are the chemical properties of hydrogen cyanide?
Hydrogen cyanide is a pale blue or colorless liquid at room temperature and is a colorless gas at higher temperatures. It has a bitter almond odor. Sodium cyanide and potassium cyanide are white powders which may have a bitter almond-like odor. Other chemicals called cyanogens can generate cyanides.
Why is hydrogen cyanide soluble in water?
Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the chemical formula HCN….Hydrogen cyanide.

How many ppm of hydrogen cyanide is dangerous?
According to ACGIH [1971], Patty [1963] reported that hydrogen cyanide at 110 to 135 ppm (120 to 150 mg/m3) might be fatal to man after 0.5 to 1 hour or later, or dangerous to life; 45 to 54 ppm (50 to 60 mg/m3) could be tolerated for 0.5 to 1 hour without immediate or late effects [Flury and Zernik 1931; Dudley et al.
What is the chemical structure of cyanide?
A cyanide is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.In inorganic cyanides, the cyanide group is present as the anion CN−. Soluble salts such as sodium cyanide and potassium cyanide are highly toxic.
What’s the chemical formula of cyanide?

Is toxicity a physical property?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.

What is the difference between cyanide and hydrogen cyanide?
Is hydrogen cyanide a strong acid?
A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water….Strong and Weak Acids and Acid Ionization Constant.
| Acid | Conjugate Base |
|---|---|
| HCN (hydrocyanic acid) (weakest) | CN− (cyanide ion) (strongest) |
What are the health effects of hydrogen cyanide?
Convulsions
What is the formula for hydrogen cyanide?
The formula of the chemical compound Hydrogen cyanide is HCN
What are the hazards of hydrogen cyanide (HCN)?
CHEMICAL DANGERS : Hydrogen cyanide (AC) is unstable with heat,alkaline materials,and water.
What are the dangers of sodium cyanide?
Agent Characteristics. Exposure to sodium cyanide can be rapidly fatal. It has whole-body (systemic) effects, particularly affecting those organ systems most sensitive to low oxygen levels: the central nervous system (brain), the cardiovascular system (heart and blood vessels), and the pulmonary system (lungs).
