b. Membuktikan sifat koagulasi pada koloid
1. Siapkan dua butir telur dan dua buah gelas kimia.
2. Gelas kimia pertama diisi dengan telur yang telah dikeluarkan dari cangkangnya.
3. Gelas kimia kedua ditambahkan 100 mL air dan diisi dengan telur yang juga telah
dikeluarkan dari cangkangnya. Rebus telur tersebut hingga matang.
4. Bandingkan kedua telur pada gelas kimia pertama (tidak dipanaskan) dan kedua
(dipanaskan). Amati dan catatlah perubahan yang terjadi!
