The base name for sulfur containing oxyacid is sulfur-instead of just sulf-. Acids are named based on their anion — the ion attached to the hydrogen. For example, table salt, or sodium chloride, consists of the Na + cation bonded to the Cl-anion to form NaCl. The name of the acid is the root of the anion followed by the suffix -ic. SO4-, sulfate ion. The prefix hydro-and the suffix -ic are then added to the root name of the anion. Salts are hygroscopic, or tend to pick up water. Since all these acids have the same cation, H +, we don't need to name the cation. A B; CO3 2-carbonate ion: H2CO3: carbonic acid: HCO3-hydrogen carbonate acid: SiO3 2-Silicate ion: NO3-nitrate ion: HNO3: nitric acid: NO2-nitrite ion: HNO2-nitrous acid There is no prefix. In simple binary acids, one ion is attached to hydrogen. What is the name and formula for the anion corresponding to sulfuric acid, H2SO4? The name of the acid is the root of the anion followed by the suffix -ous. By convention, the cation name and formula are listed before the anion name and formula. SO42-, sulfate ion. For example, N 3-is the nitride ion. SO32-, sulfate ion. ; HCl, which contains the anion chloride, is called hydrochloric acid. Convert between the structure of an acid or base and its chemical name; Key Points. The monatomic anions are named by adding -ide to the root of the name of the nonmetal that forms the anion. The resulting compound carries a neutral electrical charge. The names of the anions are below . This water is called water of hydration. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion… Monatomic Anion Names . There is no prefix. Rules for Naming Acids that Do Not Contain Oxygen in the Anion:. b. Oxyanions with -ate ending. Sulfuric acid (American spelling) or sulphuric acid (British spelling), also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4.It is a colourless, odourless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic.. Note. ; The acid name comes from the root name of the anion name. SO32-, sulfite ion.
