                  b.  Cara kondensasi
                      Pembuatan sol Fe(OH)3

                      1.  Panaskan 50 ml air di dalam gelas kimia sampai mendidih.
                      2.  Tambahkan 25 tetes larutan FeCl3 jenuh dan aduk  (Meneruskan pemanasan sampai

                          campuran berwarna merah coklat). Amati!
