For example, table salt, or sodium chloride, consists of the Na + cation bonded to the Cl-anion to form NaCl. The name of an acid is closely connected to that of the anion from which it is derived. Since all these acids have the same cation, H +, we don't need to name the cation. ite, therefore the name of the acid will end in . Expert Answer 100% (1 rating) Previous question Next question Get more help from Chegg. So then the acidic form of H2SO3 is sulphurous acid. The resulting compound carries a neutral electrical charge. In simple binary acids, one ion is attached to hydrogen. 10) MgCO 3 1) For binary acids: Add the prefix, –hydro, to the root of the non-metal’s name, and change the suffix of the anion name from –ide to … Name: Cesium Sulfite. When an anion becomes an acid, the suffix "-ite" is changed to "-ous". Anion name and Acid name Formula Anion Anion name Acid Name HF F- is fluoride hydrofluoric acid HCl Cl- is chloride hydrochloric acid HBr Br- is bromide hydrobromic acid HI I- is iodide hydroiodic acid H2S S 2-is sulfide hydrosulfic acid HNO2 NO2 is nitrite nitrous acid HNO3 NO3-is nitrate nitric acid HC2H3O2 C2H3O2-is acetate acetic acid These polyatomic ions are named with the word hydrogen in front of the name of the anion if there is one H + ion attached and dihydrogen in front of the name of the anion if two H + ions are attached. HClO, this is a chlorine and one oxygen which has the anion of ClO- which is a hypochlorite and so … And then last but not least here. HPO 4 2-is hydrogen phosphate ion. Acid Formula. Write its name and formula. Change the anion into the acid and name that acid . Formula: Cs2SO3. ATE → IC ITE → OUS Write formulas for the Following: Hunter Davis 10/15/2020 1st Period Nitric acid NHO3 Chloric acid HCIO3 Acetic acid CH3COOH Hydrobromic acid HBr Sulfurous acid H2SO3 Chlorous acid HCIO2 Hydrochloric acid H2SO3 -- X=sulfite = sulfurous acid) CHAPTER 9 … So a couple of examples. In ternary ionic compounds, you name them by combining the cation (positive) and anion (negative) and replacing the ending of the anion with -ide unless it’s a polyatomic ion, which is the case for oxalate. The first is hydrogen and the second is the oxalate (or ethanedioate). This water is called water of hydration. Acid Name Anion in Acid Acid Formula XXXXXXXXXX Name Formula XXXXXXXXXXX Hydrophosphoric acid Phosphide P-3 H3P Sulfuric acid Sulfate SO42- H2SO4 Nitrous acid Nitrite NO2- … HS-is hydrogen sulfide ion. H2SO3: Telluric Acid: H6TeO6: Tellurous Acid: H2TeO3: Tetraboric Acid: H2B4O7: Tetrathionic Acid: H2S4O6: Thiocyanic Acid: HSCN: Thiosulfurous Acid: H2S2O2: Titanic Acid: H2TiO3: Tungstic Acid: H2WO4: Uranic Acid: H2UO4: Xenic Acid: H2XeO4 H2SO3(aq) SO32- Sulfite Sulfurous acid H3PO4(aq) PO4-3 phosphate Phosphoric acid Complete the following table. By convention, the cation name and formula are listed before the anion name and formula. H 2 SO 3 the anion is sulf ite, therefore the name of the acid will end in ous – sulfurous acid. HCl= hydrochloric acid) 2. when the anion name ends in -ite the acid name is the stem of the anion with the suffix -ous followed by the word acid (ex. What is Anion of H2S? ate, therefore the acid name will end in . Cesium Sulfite. The prefix hydro-and the suffix -ic are then added to the root name of the anion. There is a separate rule for each category of acid. The stem of the anion has the suffix -ic and is followed by the word acid (ex. I know the acid name is Hydrosulfuric Acid but I'm struggling with the anion. Example Reactions: • H2SO3 + 2CsOH = Cs2SO3 + 2H2O. For example, hydrogen chloride (HCl) dissolves in water to form HCl(aq), which is named hydrochloric acid. Sulfites, salts of the anion, SO32– are found in wines as preservatives. Name Formula Systematic Name Common Name Formula Name Formula Methane CH 4 Methanoic acid Formic acid HCO 2H 1,2-Dichloroethane C 2H 4Cl 2 Ethane C 2H 6 Ethanoic acid Acetic acid CH 3CO 2H Methylamine CH 3NH 2 Propane C 3H 8 Propanoic acid Propionic acid C 2H 5CO 2H Methylammonium ion CH 3NH 3+ Butane C 4H 10 Butanoic acid Butyric acid C 3H 7CO Acid salts: Name the following acid salts. Rules for Naming Acids that Do Not Contain Oxygen in the Anion:. DO NOT use the prefix hydro. H2SO3 the anion is sulf. Where there are altenative names give both Li3PO Ca(CIO2)2 Al(SO4)s Ag2CrO Sn(NO3)4 PbC03. HCO 3-is hydrogen carbonate ion. Wiki User. This means this compound is (c) sulfurous acid. When it ionizes it forms H+ (cation) and H2PO4^1- (anion). H 2 PO 4-is dihydrogen phosphate ion. ; The acid name comes from the root name of the anion name. When an acid dissolves in water to produce a hydrogen ion and a simple nonmetal anion, the prefix hydro is used before the name of the nonmetal, and its ide ending is changed to ic acid. Anion/Polyatomic Ion. This problem has been solved! simple nonmetal anion or a polyatomic ion. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. Molar Mass: 345.8741. Since phosphorus is the more metallic element (left of sulfur), it must be named first.. Sulfur being the less metallic element is named second with an -ide ending = sulfide. ; HCl, which contains the anion chloride, is called hydrochloric acid. Lv 4. Convert between the structure of an acid or base and its chemical name; Key Points. Salts are hygroscopic, or tend to pick up water. Chemistry I Polyatomic Ions Here’s a list of common polyatomic ions and acids: Ion Name Acid Formula Acid Name NH4 + Ammonium* NO3-Nitrate HNO3 Nitric Acid NO2-Nitrite HNO2 Nitrous Acid OH-Hydroxide* HOH Water (not really an acid) CN-Cyanide HCN Hydrocyanic Acid SCN-Thiocyanate HSCN Thiocyanic Acid ClO4-Perchlorate* HClO4 Perchloric Acid Example \(\PageIndex{13}\): A compound contains 3 atoms of sulfur and 4 atoms of phosphorus. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion… Phosphoric acid is H3PO4. See the answer. The names of acids differentiate between (1) acids in which the H + ion is attached to an oxygen atom of a polyatomic anion (these are called oxoacids, or occasionally oxyacids) and (2) acids in which the H + ion is attached to some other element. Sulfurous Acid (H2SO3) - Sulfurous Acid is the chemical name of H2SO3. Acid Name. In the latter case, the name of the acid begins with hydro- and ends in -ic, with the root of the name of the other element or ion in between. Dots represen… And since there are four bonding pairs and no lone pairs, the … Summary: The protein encoded by this gene is part of the anion exchanger (AE) family and is expressed in the erythrocyte plasma membrane, where it functions as a chloride/bicarbonate exchanger involved in carbon dioxide transport from tissues to lungs.
