Cyanic acid is a chemical compound that is typically spelled using the International Phonetic Alphabet as /saɪˈænɪk ˈæsɪd/. The first syllable, "cyan," is pronounced as "sigh-an," with a long "i" sound followed by "an." The second syllable, "ic," is pronounced as "ick," which rhymes with "tick." The final syllable, "acid," is pronounced as "ass-id," with the emphasis on the first syllable. Overall, the correct spelling and pronunciation of cyanic acid are important for those working with or studying chemical compounds.
Cyanic acid is a chemical compound with the formula HOCN, consisting of one hydrogen atom bonded to one oxygen atom and one carbon atom with a nitrogen atom attached. It belongs to the family of heterocyclic compounds known as isocyanic acids. Cyanic acid is a colorless, volatile liquid that has a pungent odor similar to that of acetic acid.
In terms of its chemical properties, cyanic acid is a relatively weak acid with the potential to dissociate into a hydrogen ion and a cyanate ion in water. It decomposes slowly over time and is highly reactive, making it difficult to store and handle. Moreover, it is highly toxic and can extensively damage living tissues upon contact.
Cyanic acid has various applications in the chemical industry, particularly in the synthesis of biologically active compounds, such as pharmaceuticals and herbicides. It is also used as a precursor to other chemicals and in the production of resins, dyes, and polymers. Furthermore, cyanic acid can be utilized in the manufacturing of fire-resistant materials, fertilizers, and water treatment processes.
Although cyanic acid itself does not occur naturally, its salts, known as cyanates, are found in certain minerals and substances like urine. In nature, it may exist as an intermediate in some biologically important processes, such as the conversion of urea to ammonia. Additionally, cyanic acid can be produced as a byproduct during combustion processes involving nitrogen-containing compounds.
An acid formed by the union of oxygen and cyanogen, having the formula CNHO; in its physical properties it is very similar to protoplasm, being fluid and transparent at low temperatures and coagulable by heat.

The word "cyanic acid" originates from the term "cyan", which is derived from the Greek word "kyanos", meaning dark blue. This is because cyanic acid forms dark blue crystals when solidified. The term "acid" is used to describe a compound that donates hydrogen ions (H+) when dissolved in water, thereby producing hydrogen ions (H+). Hence, "cyanic acid" refers to an acid that contains the cyanide group (-CN).
