  1. Starter wc 19.11.12 • Halogens Displacement reactions • For each of the following write down what you would observe. Where a reaction occurs write an IONIC equation: • Br 2(aq) + I-(aq) • Br-(aq) + I2(aq) • I2(aq) + Cl-(aq) • Cl2(aq) + NaBr(aq) • Br2(aq) + KCl(aq) • Cl2(aq) + MgBr2(aq) • AlCl3(aq) + I2(aq)

  2. Starter wc 19.11.12 • Halogens Displacement reactions • For each of the following write down what you would observe. Where a reaction occurs write an IONIC equation: • Br2(aq) + I-(aq) 2Br- + I2(aq) Orange solution formed • Br-(aq) + I2(aq) no reaction – solution remains brown • I2(aq) + Cl-(aq) no reaction – solution remains brown • Cl2(aq) + 2Br-(aq)  2Cl-(aq)+ Br2(aq)Orange solution forms • Br2(aq) + KCl(aq) no reaction solution remains orange • Cl2(aq) + 2Br- (aq) Br2(aq) + 2Cl-(aq)Orange solution forms • AlCl3(aq) + I2(aq)  no reaction – solution remains brown
