  1. The Activity SeriesFor Single Replacement Reactions Text Reference: 8.3 (pg. 265 - 267)

  2. No, Ni is below Na Yes, Li is above Zn Yes, Al is above Cu Yes, Fe is above Cu • We have looked at several reactions: Fe + CuSO4  Cu + Fe2(SO4)3 Li + H2O  LiOH + H2 • Such experiments reveal trends. The activity series ranks the relative reactivity of metals. • An activity series allows us to predict whether or not certain chemicals will undergo single replacement reactions when mixed. • Metals near the top of the series are most reactive and will displace the metals near the bottom. • Which of these will react? Fe + CuSO4  Ni + NaCl  Li + ZnCO3  Al + CuCl2  Cu + Fe2(SO4)3 NR (No Reaction) Zn + Li2CO3 Cu + AlCl3

  3. cold H2O • Hydrogen is the only nonmetal listed. H2 may be displaced in S.R. reactions. • It can also be given off when a metal reacts with H2O (producing H2 + metal hydroxide). • A reaction with H2O depends on metal reactivity & water temperature. • Will Mg react with H2O? hot H2O steam Only if the H2O is hot/steam. Mg + H2O  H2 + Mg(OH)2 • Will Zn replace H? • Zn + HCl  H2 + ZnCl2 Complete these reactions: Al + H2O(steam)  Cu + H2O  Ca + H2SO4  Na + H2O  H2 + Al(OH)3 NR (No Reaction) H2 + CaSO4 H2 + NaOH

  4. Other Activity Series Information • All metals will have a specific place in the activity series. For simplicity, only the most common metals are shown. • The metals near the top of the activity series are more reactive because their valence electrons are more easily removed. • On tests and quizzes the activity series will be given to you. • You must remember that the metals appearing towards the top are more reactive than the metals appearing towards the bottom…
