Na Al 3 S 2 2Ca 2 PO 4 3 3Cl Review forming ions Ionic ie salt refers to ve ion plus ve ion Usually this is a metal nonmetal or metal polyatomic ion eg NaCl NaClO. Anions. Cations. Naming Ions. Naming Ionic Compounds. Writing Ionic Formulas. Identify some Anions and . Cations. Anions. Cations. Metals Lose Electrons . (. Cations. = +). Nonmetals tend to gain electrons (Anions = -). Aqueous solutions of Sodium Hydroxide and Copper (II) Chloride combine to form an aqueous solution of . sodium. . chloride and . solid blue Copper Hydroxide . Write a skeleton equation. Balance the equation.. Learning Goals …. … write an ionic and net ionic equation. … use qualitative analysis (flame test, solution colour and solubility) to identify ions in a solution. Let’s take a closer. look at the reaction between. The Mole. REVISION. Formulae tell you how many of each atom are in a molecule.. Different atoms have different masses.. Level 4. NEW LEARNING. Formulae and balanced equations. Formula Mass and the mole. Chapter 7. An . ion. is an atom that has gained or lost electrons from the valence shell.. Valence electrons. are the electrons contained in the highest occupied energy level. These electrons will mostly determine the chemical properties of the element. Focus on equations with a precipitate.. Total Ionic Equations. Write the equation . (synthesis, decomposition, etc. .). check . for reactants and products that are . soluble. or . insoluble. .. We usually assume the reaction is in . Lesson 2. Learning outcomes. C12-1-02: . Perform a laboratory activity to develop a set of solubility rules. C12-1-03:. Use a table of solubility rules to predict the formation of a precipitate. Solubility rules. C. 6. H. 12. + 9 O. 2. . . 6 CO. 2. + 6 H. 2. O. Cl. 2. + 2KBr . . Br. 2. . + 2KCl. NaOH. + KNO. 3. . . . NaNO. 3. + . KOH. 2H. 2. . + O. 2. . . . 2H. 2. O. Will this reaction go forward? Why or why not? If so, balance the equation.. Split up the ionic compounds into their respective ions. . Combine a cation with an anion from the ions in solution. There are 2 possible combinations. These are the possible products.. Check the solubility rules to determine which of the possible products is not soluble. This is the precipitate. There may be 1, 2, or no precipitates.. Net ionic equations are useful in that they show only those chemical species directly . participating in . a chemical . reaction. The keys to being . able to . write net ionic equations are the ability to recognize monatomic and polyatomic ions, . HOMEWORK. Do all . odd exercises . in this book on a separate sheet of paper.. DO NOT WRITE IN THE BOOK.. Chapter 1. Symbols and Nomenclature of the elements. There is interesting info where the elements got their name, but nothing we will cover.. Describing Chemical Reactions. Chemical Reaction – process in which one or more substances are changed into one or more different substances. Reactants – original substance. Products – resulting substance . Module 7: Introduction to chemical reactions. 7.1: . Chemical equations must be balanced. 7.2: . Aqueous solutions and solubility. 7.3: . Precipitation reactions form solids; complete and net ionic.
