Name the anion obtained by removing one oxygen atom from the perbromate ion, BrO4–. Give the chemical formulas for (a) hydrobromic acid, (b) carbonic acid. The metals form the cations, and the nonmetals form the anions. Names and Formulas of Ionic Compounds In this section we consider the basic rules for naming three categories of inorganic compounds: ionic compounds, molecular compounds, and acids. The first part of the element's name, such as “chlor” for chlorine or “sulf” for sulfur, goes in the blank. An exception occurs when the compound contains oxygen and chlorine, bromine, or iodine (any halogen except fluorine), in which case oxygen is written last. FIGURE 2.25 can help you remember the charge and number of oxygen atoms in the various oxyanions. The names of compounds with these ions consist of the metal and the anion. (b) The cation is Ba2+, the barium ion, and the anion is OH–, the hydroxide ion: barium hydroxide. If a metal can form cations with different charges, the positive charge is indicated by a Roman numeral in parentheses following the name of the metal: Ions of the same element that have different charges have different properties, such as different colors (FIGURE 2.23). Formulas of Binary Inorganic Compounds . a. Cations formed from metal atoms have the same name as the metal: //. It is published in Nomenclature of Inorganic Chemistry (which is informally called the Red Book). The names and chemical formulas of compounds are essential vocabulary in chemistry. (e in b.c))if(0>=c.offsetWidth&&0>=c.offsetHeight)a=!1;else{d=c.getBoundingClientRect();var f=document.body;a=d.top+("pageYOffset"in window?window.pageYOffset:(document.documentElement||f.parentNode||f).scrollTop);d=d.left+("pageXOffset"in window?window.pageXOffset:(document.documentElement||f.parentNode||f).scrollLeft);f=a.toString()+","+d;b.b.hasOwnProperty(f)?a=!1:(b.b[f]=!0,a=a<=b.g.height&&d<=b.g.width)}a&&(b.a.push(e),b.c[e]=!0)}y.prototype.checkImageForCriticality=function(b){b.getBoundingClientRect&&z(this,b)};u("pagespeed.CriticalImages.checkImageForCriticality",function(b){x.checkImageForCriticality(b)});u("pagespeed.CriticalImages.checkCriticalImages",function(){A(x)});function A(b){b.b={};for(var c=["IMG","INPUT"],a=[],d=0;db||1342177279>>=1)c+=c;return a};q!=p&&null!=q&&g(h,n,{configurable:!0,writable:!0,value:q});var t=this;function u(b,c){var a=b.split(". Acids containing anions whose names end in -ate or -ite are named by changing -ate to -ic and -ite to -ous and then adding the word acid. Number of problems: 5 10 25 50 100! The most common of these ions are shown in boldface. SAMPLE EXERCISE 2.12 Determining the Names of Ionic Compounds from Their Formulas. In chemical nomenclature, the IUPAC nomenclature of inorganic chemistry is a systematic method of naming inorganic chemical compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC). For our present purposes, an acid is a substance whose molecules yield hydrogen ions (H+) when dissolved in water. inorganic compounds: all other compounds they may contain carbon but most often without … Practice writing formulas from names and names from formulas using the examples below. Name the acids (a) HCN, (b) HNO3, (c) H2SO4, (d) H2SO3. Chemical compounds are substances formed by two or more elements interrelated, thus giving rise to an entirely new and different substance. Names and formulas of ionic compounds. 1) Sodium bicarbonate : Baking powder: NaHCO3 2) Copper Sulphate : Blue Vitriol : CuSO4 XH20 3) Calcium Oxychloride : Bleaching powder : CaOCL2 4) Trichloro Methane : Chloroform : CaOCL2 5) Calcium Carbonate : Chalk (Marble) : CaCo3 6) Potassium Hydroxide : Caustic Soda : NaOH 7) Solid Carbondiaoxide : Dry Ice : CO2 8) Magnesium Sulphate : Epsom : MgSO4 9) Caustic Potash : Potassium Hydroxide : KOH 10) Calcium Sulphate : Gypsum : CaSo4 2H2O 11) Ferrous Sulphate : Green Vitriol : FeS… Compounds of carbon are classified as organic when carbon is bound to hydrogen. 4. Nomenclature of Inorganic Compounds (KEY) CHEM 1A 1. a. The prefixes per- and hypo- are retained in going from the anion to the acid. Thus, you can predict that the substance named hydrogen chloride has the formula HCl, containing one H+ to balance the charge of one Cl–. If a metal can have multiple charges, the positive charge is indicated by a Roman numeral in parentheses following the name … This and the following section describe the rules for naming simple covalent compounds, beginning with inorganic compounds and then turning to simple organic compounds that contain only carbon and hydrogen. (2.8) 2.8b Name binary and oxyacids using the systematic IUPAC method; write the chemical formulas of acids given… Learn with flashcards, games, and more — for free. The name of an ionic compound also gives you information about the oxidation numbers of the elements. Start studying Chapter 6: Inorganic and Organic Compounds- Names and Formulas. Two HCO3– ions are needed to balance the positive charge of Ca2+, giving Ca(HCO3)2. In the second period the charges also increase from right to left, from 1– for NO3– to 2– for CO32–. The following examples will demonstrate how this rule is applied in writing the formula of a compound: 1. Most of the compounds are binary compounds, i.e. Name the compounds (a) SO2, (b) PCl5, (c) Cl2O3. The names of monatomic anions are formed by replacing the ending of the name of the element with -ide: A few polyatomic anions also have names ending in -ide: b. Polyatomic anions containing oxygen have names ending in either -ate or -ite and are called oxyanions. SAMPLE EXERCISE 2.11 Determining the Formula of an Oxyanion from Its Name, Based on the formula for the sulfate ion, predict the formula for (a) the selenate ion and (b) the selenite ion. The substance on the left is Fe3O4, which contains Fe2+ and Fe3+ ions. Search Search Answers: (a) ammonium bromide, (b) chromium(III) oxide, (c) cobalt(II) nitrate, SAMPLE EXERCISE 2.13 Determining the Formulas of Ionic Compounds from Their Names. Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Why is CrO named using a Roman numeral, chromium(II) oxide, whereas CaO is named without a Roman numeral, calcium oxide? An older method still widely used for distinguishing between differently charged ions of a metal uses the endings -ous and -ic added to the root of the element's Latin name: Although we will only rarely use these older names in this text, you might encounter them elsewhere.
