Disperse system Comparison of nature of between condensations, colloid and suspension. Solution (molecular dispersion) Colloid (colloid dispersion) Suspension (hard dispersion) Example : Sugar solution in water, alcohol solution. Example : Mix of milk and water Example : Mix of flavour an water, coffee in water Homogeneous can not be differed even using ultra microscope All particles, the dimensions of (the length, the width, the thickness) < 1 nm One phase Stable Can not be filtered Microscopicly, homogeneous characteristic but it is homogeneous if we observe with ultra microscope Dimensional particle between 1 nm-100 nm Two phase Generally stable Can be filtered with ultra filtered Heterogeneous One of or all dimension of the particles > 100nm Can be filtered with filtered paper Hal.: 4 Isi dengan Judul Halaman Terkait

Colloid Grouping Based on dispersed phase and disperser media, colloid system can be grouped; Dispersed phase Disperser phase Types of colloid Example Solid Gas Solid aerosol Smoke, dust on air (airborne) Liquid Sol Golden sol, ink, paint Solid sol Colorful glass, combining metal, black diamond Liquid aerosol Fog, cloud, bugs spray Emulsion Milk, ice cream, coconut mink, fish oil, ketchup Jelly, mayonnaise, pearl, butter Soapsuds, mixed cream Foam Rubber foam, purmice Hal.: 6 Isi dengan Judul Halaman Terkait

Absorbtion Is the system of colloid that can absorb particle or ion or other compound Absorbtion surface is called absorbs Absorbtion until inside lining is called adsorbs Hal.: 9 Isi dengan Judul Halaman Terkait

Coagulation Coagulation which is caused by gravitational force and happened if colloid system in a state of didn't charge. Colloid haves the character of neutral if; Applies Electrophoretic Principle; Electrophoresis process is movement of colloid particles which charges to electrode with charge which at the oposite. When this particle reachs electrode, hence colloid system will lose its(the charge and haves the character of neutral. Addition of other colloid with charge which at the oposite; When colloid haves positif charge mixed with colloid to charge negativity, hence the charge would be each other eliminate and haves the character of neutral. Hal.: 10 Isi dengan Judul Halaman Terkait

Addition of Electrolyte; If an electrolyte added at colloid system, hence particle colloid which haves negative charge adsorption of colloid will with positive charge ( cation) from electrolyte. So do on the contrary, particle positive adsorption of negativity particle will ( anion) from electrolyte. From adsorption is upper, hence happened coagulation. Bubbling; Increase of colloid system temperature causes hammering between sole particles with water molecules increases many. This matter discharges electrolyte adsorption at colloid surface. As a result particle doesn't charge. Hal.: 11 Isi dengan Judul Halaman Terkait

Colloid Liofil and Colloid Liofob
Colloid liofil (fond of liquid) is the system of colloid of which its dispersed phase has a bigger absorbing power. Example; starch, soap and detergent dispersion Hal.: 12 Isi dengan Judul Halaman Terkait

Liofob colloid ( doesn't like dilution), that is if particle is dispersion it is having feebler relative adsorbs energy power Example; gold dispersion, sulfur in water Hal.: 13 Isi dengan Judul Halaman Terkait

Dispersion Can be done by the way of mechanic and also way of chemistry where big particle turned into colloid particle, covers; Way Of Mechanic; This way done from big particle Iump then refined by the way of grinder or hulling. Way Of Bow Bredig; Way Of Bow Bredig applied to make metal soles with electrical interest hop. Way Of Peptization; Way of peptization is making of colloid from harsh item or from a sediment with help of peptization ( billows). Example : Jelly peptization by water ; Rubber by gasoline.
