WebDec 30, 2024 · As we know, Sodium cyanide is formed when NaOH (Strong base) reacts with HCN (Weak acid). They react with each other in the molar ratio of 1:1. ⇒ NaOH + HCN → NaCN + H 2 O As per the concepts of salts, a combination of a strong base and weak acid leads to the formation of basic salt. Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a pKa of 9.2. It partially ionizes in water solution to give the cyanide anion, CN . A solution of hydrogen cyanide in water, represented as HCN, is called hydrocyanic acid. The salts of the cyanide anion are known as cyanides.

WebYou can see that hydroxide ion is a stronger base than ammonia (NH 3 ), because ammonium (NH 4+, pK a = 9.2) is a stronger acid than water (pK a = 14.00). The stronger the conjugate acid, the weaker the conjugate base.
