Here are the answers to Question 3: i) What happens when bromine reacts with: a) Potassium chloride? Bromine is less reactive than chlorine. Therefore, bromine cannot displace chlorine from potassium chloride. No reaction occurs. b) Potassium iodide? Bromine is more reactive than iodine. Therefore, bromine will displace iodine from potassium iodide, forming potassium bromide and iodine. Bromine displaces iodine to form potassium bromide and iodine. ii) Write a complete balanced equation when chlorine reacts with: a) Calcium bromide Chlorine is more reactive than bromine, so it will displace bromine from calcium bromide. Cl_2(aq) + CaBr_2(aq) CaCl_2(aq) + Br_2(aq) b) Sodium iodide Chlorine is more reactive than iodine, so it will displace iodine from sodium iodide. Cl_2(aq) + 2NaI(aq) 2NaCl(aq) + I_2(aq) 3 done, 2 left today. You're making progress.
