How Do You Spell THIOSULPHURIC ACID?

Pronunciation: [θˌa͡ɪə͡ʊsəlfjˈʊɹɪk ˈasɪd] (IPA)

The spelling of the word "thiosulphuric acid" may confuse some individuals due to the use of the suffix "-ic" instead of "-ous" usually found in naming oxyacids. However, this spelling is based on the IUPAC guidelines for inorganic compound nomenclature. The word is pronounced /ˌθaɪəʊsʌlˈfjʊərɪk/ in IPA transcription, with the stress on the second syllable. The prefix "thio-" refers to a sulfur atom replacing an oxygen in the anion, and "sulphuric" relates to the presence of a sulfate group with a sulfur-oxygen double bond.

THIOSULPHURIC ACID Meaning and Definition

1. Thiosulphuric acid is a chemical compound with the molecular formula H2S2O3. Also known as hyposulphurous acid, it is a weak acid that combines sulfur, hydrogen, and oxygen atoms.

   Thiosulphuric acid is formed by the addition of sulfur dioxide gas to an aqueous solution of sodium thiosulphate. It consists of two sulfur atoms bonded to three oxygen atoms and two hydrogen atoms. The compound is an intermediate in the Sulfur cycle and is commonly used in various industrial processes.

   Thiosulphuric acid is a colorless liquid that has a pungent odor. It is highly reactive and decomposes easily, especially under high temperatures, releasing toxic sulfur dioxide gas. The compound is mostly used as a reducing agent and a buffer in chemical reactions.

   In industries, thiosulphuric acid finds applications in the manufacturing of dyes, pharmaceuticals, and photographic chemicals. It is also utilized in the metal finishing industries to remove impurities from metal surfaces as well as in the extraction of gold and silver from their ores.

   In addition to its industrial uses, thiosulphuric acid is popularly used in laboratories for various purposes. For instance, it is employed in the iodometric determination of various substances, such as chlorine and hydrogen peroxide. Furthermore, it is used in the preparation of other chemical compounds.

   Overall, thiosulphuric acid is a versatile chemical compound that has numerous applications in various industries and laboratory settings due to its unique properties and reactivity.

2. Hyposulphurous acid, a sulphuric acid in which an atom of oxygen has been replaced by sulphur.

Etymology of THIOSULPHURIC ACID

The word "thiosulphuric acid" has an etymology derived from two components: "thio" and "sulphuric acid".

1. "Thio" is derived from the Greek word "theion", meaning "sulfur". It is commonly used as a prefix to indicate the substitution of an oxygen atom with a sulfur atom in chemical compounds.

2. "Sulphuric acid", on the other hand, has its etymology from the Latin word "sulfur" for "sulfur" and the suffix "-ic acid" indicates that it is an acid. "Sulphuric acid" refers to a strong acid composed of hydrogen, sulfur, and oxygen molecules.

Overall, "thiosulphuric acid" describes an acid that includes a substitution of oxygen with sulfur, thereby indicating the presence of sulfur in the compound.
