An acid is a substance that dissociates into hydrogen ions (H +) and anions in water. A quick way to identify acids is to see if there is an H (denoting hydrogen) in front of the molecular formula of the compound.
Learning Objectives. Derive names for common types of ionic compounds using a systematic approach. Nomenclature, a collection of rules for naming things, is important in science and in many other situations. This section describes an approach that is used to name simple ionic such as NaCl, and CaCO 3.
Monatomic anions are named by adding the suffix -ide to the root of the name of the parent element; thus, Cl − is chloride, O 2− is oxide, P 3− is phosphide, N 3− is nitride (also called azide), and C 4− is carbide.
Gold(III) chloride, traditionally called auric chloride, is an inorganic compound of gold and chlorine with the molecular formula Au 2 Cl 6. The "III" in the name indicates that the gold has an oxidation state of +3, typical for many gold compounds.
The following website provides practice with naming chemical compounds and writing chemical formulas. You can choose binary, polyatomic, and variable charge ionic compounds, as well as molecular compounds.
From a list of almost 2000 names and formulas, students will be given the opportunity to practice their ability to name ionic compounds, given the formula, and determine the formula given the name. A. B. Lithium Nitrite. LiNO 2. Lithium Nitrate. LiNO 3. Lithium Hydrogen Sulfate. LiHSO 4.
