Chromium (III) sulphate solution with: Ammonia, Sodium Carbonate, Pottasium Thiocyanate and Pottasiumm Hexacyanoferate (II)
Iron (II) sulphate solution with: Ammonia, Sodium Carbonate, Pottasium Thiocyanate and Pottasiumm Hexacyanoferate (II)
Iron (III) sulphate solution with: Ammonia, Sodium Carbonate, Pottasium Thiocyanate and Pottasiumm Hexacyanoferate (II)
