BÀI số 5 ĐIỀU CHẾ CÁC HỆ KEO –KHẢO SÁT MỘT SỐ TÍNH CHẤT CỦA CHÚNG –KHẢO SÁT MỘT SỐ TÍNH CHẤT CỦA CHÚNG

Hôm nay chúng ta sẽ đi tìm hiểu về một số tính chất của các hệ keo, đầu tiên về mục đích nghiên cứu , cơ sở lý thuyết va tiến hành chế tạo Son S , Son cooloophan bằng phương pháp dung môi. Chế tạo Son AgI bằng phản ứng trao đổi , chế tạo keo Fe(OH)3 bằng phản ứng thủy phân ,chế tạo nhũ tương và sự đảo pha nhũ tương và cuối cùng là xác định ngưỡng keo tụ của son Fe(OH)3 bằng Na2SO4 ( hoặc K2SO4 ).
