  2. Karakteristiklarutan, koloid, dansuspensi 1 Å = 10-4 µm = 10-10 m

  3. Contoh -larutanNaCl - larutan protein - es -larutangula - plasma darah -eritrositdalamdarah -larutanpati

  4. Mendeteksikeberadaankoloid : Efek Tyndall Koloid larutan

  5. KlasifikasiKoloid • Berdasarkansifatfisiksenyawaterdispersidan medium • pendispersi

  6. Sol dan Gel Sol dan gel  liofilik Sol  partikelpadatdidispersikandalamfasacair  kadang-kadangprosesnyamembutuhkan pemanasandanpengadukan Protein danpati sol dan gel

  7. Berdasarkanbentukpartikel • - isotrop (koloidspherical)  contoh: globulin • - anisotrop (koloid linear)  contoh: filamen • Berdasarkanukuranpartikelkoloid • - sistemmonodispersi • - sistempolidispersi

  8. Berdasarkaninteraksiantarasenyawaterdispersidan • medium endispersi • - liofilik protein • asamnukleat • emulsifier • - liofobik sol emas, sol perak • sulfidalogam • hidroksidalogam • Berdasarkansenyawaterdispersi • - suspensoid(suspensilogam) • - koloidasosiatif (micellar)  sabun, detergen, emulsifier • - koloidmakromolekular  protein, polisakarida, plastik • polimer
