  1. Types of Reactions Single & Double Displacement

  2. + +  Cl Cl Cl Cl Zn Zn Cu Cu Types: Single displacement Example: Zn + CuCl2 General: AB + C  AC + B

  3. Single Displacement Reactions: A variety of predictions can be made based on the activity series of metals: potassium (K) most reactive never found form stable sodium (Na) calcium (Ca) “free” in nature compounds magnesium (Mg) aluminum (Al) zinc (Zn) iron (Fe) nickel (Ni) tin (Sn) lead (Pb) hydrogen (H) copper (Cu) mercury (Hg) silver (Ag) platinum (Pt) found “free” form unstable gold (Au) least reactive in nature compounds

  4. No, Ni is below Na Yes, Li is above Zn Yes, Al is above Cu Yes, Fe is above Cu The activity series ranks the relative reactivity of metals. It allows us to predict if certain chemicals will undergo single displacement reactions when mixed: metals near the top are most reactive and will displacing metals near the bottom. Q: Which of these will react? Fe + CuSO4  Ni + NaCl  Li + ZnCO3  Al + CuCl2  Cu + Fe2(SO4)3 NR (no reaction) Zn + Li2CO3 Cu + AlCl3

  5. a. Metal + Acid/Water: Any metal above hydrogen in the activity series will displace hydrogen gas froman acid or water (although sometimes heat must be applied to increase the reaction rate to the point where the reaction is noticeable) Examples: 1. Zn(s) + 2HCl(aq)  ZnCl2(aq) + H2(g) 2. Cu(s) + HCl(aq)  no reaction 3. Cu(s) + H2O(l)  no reaction

  6. cold H2O hot H2O More Practice Q: will Mg react with H2O? A: No for cold, yes if it is hot/steam Mg + H2O  steam H2 + Mg(OH)2 acid Q: Zn + HCl  H2 + ZnCl2 Complete these reactions: Al + H2O(steam)  Cu + H2O  Ca + H2SO4  Na + H2O  H2 + Al(OH)3 NR H2 + CaSO4 H2 + NaOH

  7. b. Metal + Metallic Compound(aq): A metal will displace from a compound (in solution) any other metal which is located below it in the activity series of metals. Examples: 1. Mg(s) + ZnI2(aq)  MgI2(aq) + Zn(s) 2.Ni(s) + ZnI2(aq)  no reaction

  8. A variety of predictions can also be made based on the activity series of nonmetals: fluorine (F) most reactive never found form stable Chlorine (Cl) “free” in nature compounds bromine (Br) oxygen (O) iodine (I) found “free” form unstable sulphur (S)least reactive in nature compounds A nonmetallic element will displace from a compound (in solution) any nonmetal that is located below it in the activity series of nonmetals. Examples: 1. F2(g) + 2NaBr(aq)  2NaF(aq) + Br2(aq) 2. I2(s) + NaBr(aq)  no reaction

  9. Ca Ca  + + Mg Mg S S O O Types: Double displacement Example: MgO + CaS General: AB + CD  AD + CB

  10. Double Replacement Reactions • Double Replacement Reactions occur when a metal replaces a metal in a compound and a nonmetal replaces a nonmetal in a compound • Compound + compound  product + product • AB + CD  AD + CB

  11. Double Replacement Reactions • Think about it like “foil”ing in algebra, first and last ions go together + inside ions go together • Example: AgNO3(aq) + NaCl(s)  AgCl(s) + NaNO3(aq) • Another example: K2SO4(aq) + Ba(NO3)2(aq)  KNO3(aq) + BaSO4(s)

  12. Practice • Predict the products. • HCl(aq) + AgNO3(aq)  • CaCl2(aq) + Na3PO4(aq)  • Pb(NO3)2(aq) + BaCl2(aq)  • FeCl3(aq) + NaOH(aq)  • H2SO4(aq) + NaOH(aq)  • KOH(aq) + CuSO4(aq)  AgCl(aq) + HNO3(aq) Ca3PO4(aq) + NaCl(aq) PbCl2(aq) + Ba(NO3)2(aq) Fe(OH)3(aq) + NaCl(aq) H2O(aq) + Na2SO4(aq) K2SO4(aq) + Cu(OH)2(aq)
