Is Hcn A Weak Acid
What is Hydrocyanic Acrid?
Hydrocyanic acid is a liquid of hydrogen cyanide in h2o. The chemical formula of Hydrocyanic acrid is HCN. Hydrocyanic acrid is a colourless liquid whose vapour is lighter than air and dissipates speedily. It is unremarkably sold commercially as an aqueous solution containing 2 to 10% hydrogen cyanide. The aqueous solutions of hydrogen cyanide decompose slowly to form ammonium formate. Information technology is a very poisonous colourless gas with a characteristic fragrance of bitter almonds. It is a dangerous transparent liquid its storage and transport are prohibited.
Other names – Prussic acid, acetonitrile, formonitrile

Chemical Properties ofHydrogen cyanide-HCN
- Hydrocyanic acid reacts with bases like sodium hydroxide forms sodium cyanide and water. The chemical equation is given below.
HCN + NaOH → NaCN + H2O
- Hydrocyanic acid reacts with potassium hydroxide forms potassium cyanide and water. The chemical equation is given below.
HCN + KOH → H2O + KCN
Uses ofHydrogen cyanide-HCN
- Used every bit a fumigant to kill pests such as rodents in warehouses, grain storage bins, greenhouses and holds of ships where its high toxicity and power to penetrate obscure spaces are advantageous.
- Used in the manufacture of cyanide salts, acrylonitrile and dyes. It is also used as a horticultural fumigant.
- Used as a highly valuable forerunner in the production of several chemicals.
Oft Asked Questions- FAQs
1. Is hydrocyanic acid harmful?
Hydrocyanic acrid is one of the most speedily interim poisons, and it is therefore used especially every bit a suicidal or homicidal amanuensis. Minor concentrations of hydrocyanic acid are inhaled, causing headache, dizziness, feeling of suffocation, nausea, etc.
2. Is hydrogen cyanide still used?
Hydrogen cyanide is used in the industry of cyanide salts, acrylonitrile and dyes. It is besides used every bit a horticultural fumigant. It is used commercially for fumigation, electroplating, mining, chemical synthesis, and the production of synthetic fibres, plastics, dyes, and pesticides.
3. What is the molecular shape of HCN?
The molecular shape of HCN is linear.
4. What is the hybridization of HCN?
In HCN construction the hybridisation of carbon atom is sp hybridisation. There are two sigma bonds, C-H and C-N. The number of sigma bonds is equal to the number of hybrid orbitals formed.
v. Is HCN a strong or weak acid?
HCN is a weak acid. A weak acid has a strong conjugate base. CN- is a strong conjugate base.
