Single Replacement Reactions

Single replacement reactions occur when a single uncombined element replaces another element in a compound. 2 Fe(s) + 3 Cu. SO 4 (aq) Fe 2(SO 4)3 (aq) + 3 Cu (s)

The Activity Series Metals Lithium Potassium Strontium Calcium Sodium Magnesium Aluminum Zinc Chromium Iron Nickel Tin Lead Hydrogen Copper Silver Mercury Platinum Gold Non-metals F 2 Cl 2 Br 2 I 2 Al is more active than H Cl 2 is more active than I 2 Decreasing Activity

The Activity Series allow us to predict whether or not a SR reaction will happen: If the single element is more active on the chart compared to the one in the compound, the reaction will happen. If it is not, then there is no reaction. most active Mg(s) + 2 HCl (aq) Ni(s) + Mg. Cl 2 (aq) + H 2(g) No reaction

Cl 2(g) + Mg. Br 2 (aq) Mg. Cl 2 (aq) + Br 2(l) 2 Na(s) + 2 HOH (l) 2 Na. OH (aq) + H 2(g) 2 Al(s) + 3 H 2 SO 4 (aq) Al 2(SO 4)3 (aq) + 3 H 2(g)

Complete each Reaction. F 2(g) + 2 Na. Cl (aq) 2 Na. F(aq) + Cl 2(g) + Na. F (aq) No Reaction Pb (s) + Cu. SO 4 (aq) Pb. SO 4 (s) + Cu(s) F is more active Pb is more active Low solubility Pb (s) + Al(NO 3)(3)(aq) No Reaction Al is more active Iron metal is added to phosphoric acid. 2 Fe(s) + 2 H 3 PO 4(aq) 2 Fe. PO 4(aq) + 3 H 2(g) Fe is more active
