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.. SO42-, sulfate ion. Acids are named based on their anion — the ion attached to the hydrogen. SO32-, sulfite ion. 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 Note. Convert between the structure of an acid or base and its chemical name; Key Points. b. Oxyanions with -ate ending. SO32-, sulfate ion. The monatomic anions are named by adding -ide to the root of the name of the nonmetal that forms the anion. In simple binary acids, one ion is attached to hydrogen. Monatomic Anion Names . For example, table salt, or sodium chloride, consists of the Na + cation bonded to the Cl-anion to form NaCl. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion… There is no prefix. There is no prefix. This water is called water of hydration. The base name for sulfur containing oxyacid is sulfur-instead of just sulf-. The name of the acid is the root of the anion followed by the suffix -ic. Salts are hygroscopic, or tend to pick up water. 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. The names of the anions are below . Since all these acids have the same cation, H +, we don't need to name the cation. Rules for Naming Acids that Do Not Contain Oxygen in the Anion:. ; HCl, which contains the anion chloride, is called hydrochloric acid. ; The acid name comes from the root name of the anion name. For example, N 3-is the nitride ion. The prefix hydro-and the suffix -ic are then added to the root name of the anion. SO4-, sulfate ion. The resulting compound carries a neutral electrical charge. What is the name and formula for the anion corresponding to sulfuric acid, H2SO4?
