Transcript of "Double replacement reactions with net ionic and spectators"

  1. 1. Chapter 8 Chemical Equations !Word Equation – the names of the substances are given inwords for you to interpret.Zinc plus Hydrochloric Acid yields Zinc chloride plus Hydrogen gas ! REACTANTS PRODUCTS
  2. 2. Interpreting chemical equations Al (OH)3 + 3HCl AlCl3 + 3 H2O Reacts To make And threeOne with 3 one FU of moleculesformula molecules aluminum of waterunit of of HCl chloridealuminumhydroxideSO WHAT DOES THIS MEAN????
  3. 3. Ions in water solutionWhen ionic substances dissolve in water their crystal latticestructure breaks up and they exist as IONS in water !NaCl yields Na + plus Cl -KCl yields K+ plus Cl-
  4. 4. Ionic equations and spectators !• Ionic equations simply show what is happening to the ions taking part in a reaction.• Spectator ions are those which do not actually participate in the reaction.• See solubility chart page 860
  5. 5. Write the NET ionic equation which occurs when aqueous solutions of zinc chloride and potassium hydroxide react. ZnCl2 (aq) + 2 KOH (aq) Zn (OH)2(s) + 2 KCl(aq)Zn+2 + 2Cl-1 + 2K+ + 2OH- Zn(OH)2(s) + 2K+ + 2Cl- Zn+2 + 2OH- Zn(OH)2(s)
  6. 6. Predict the productsWhen K reacts with MgF 2 Mg + KF When Mg reacts with KF NO REACTION
  7. 7. Predict the productsNaOH + KClNaNO3+ KBrAmmonium Carbonate + Magnesium carbonate as precipitate andMagnesium Chloride ammonium ions and chloride ions as spectators
