"Hard" water contains mainly salts of Ca2+ and Mg2+, both of which form many insoluble salts. You have a water sample and need to determine whether it contains Ca2+ and/or Mg2+. When you add ammonia to the solution, followed by ammonium chloride and ammonium oxalate, a white precipitate of CaC2O4 should form if Ca2+ is present. What is the purpose of adding the ammonium chloride to the reactant mixture? a. The chloride ion helps to form the calcium chloride precipitate....
