Group 7

• How do forces arise between the molecules of Cl2

  • a temporary dipole is in induced in a molecule of chlorine due to random movement
  • this induces a dipole in a neighbouring molecule
  • there is temporary attraction between the delta plus and minus
• What is the reaction between water and chlorine?

  CL2 + H2O ⇌  HCLO + HCL
• Why is chlorine added to water?

  it kills bacteria
• What is the reaction between chlorine and cold, aqueous sodium hydroxide?

  CL2 + 2NaOH ⇌  NaClO + NaCl + H2O
• chlorine is not strong enough to reduce sulfuric acid
• What is the reaction between AgCl and ammonia?

  AgCl + 2NH3 ----> [Ag(NH3)2]+ + Cl-
