Kinds Of Colloid Colloid system consisted of to be biphase, that is dispersion phase and medium pendispersi. Both the phases, can form hydrogen, solid matter or forms gas. Based on the relation of between dispersion phases and dispersion medium, hence colloid earns we to classify A. Colloid formed by its(the dispersed phase gas in its(the pendispersi medium liquid is effervescence or spume. Example for this colloid is protein shaked high-speedly. Hal.: 10 Isi dengan Judul Halaman Terkait

Continuation B. Effervescence or solid spume is colloid type which its(the dispersed phase its(the gas and pendispersi medium solid, this colloid type cans be in the form of pumice and foam rubber. C. Colloid with liquid dispersed phase and its(the pendispersi medium gas is recognized as liquid aerosol. Example of this colloid is fog, cloud, hair ossifying ( hair spray) and douche perfume Hal.: 11 Isi dengan Judul Halaman Terkait

Continuation D. Emulsion is colloid type formed by liquid dispersed phase in medium pendispersi liquid. Emulsion earns we to find milky, coconut mink, mayonaise and cod. E. Colloid compiled by liquid dispersed phase in solid pendispersi medium called as with solid emulsion or gel. This colloid often we meet in cheese, butter , jelly, solid polish and or solid glue Hal.: 12 Isi dengan Judul Halaman Terkait

Continuation F. Solid aerosol is compiled by solid dispersed phase with its(the gaseous dispersion medium. Its(the example smoke and dirt on the air). G. Sole is colloid which its(the dispersed phase forms solid with its(the pendispersi medium forms liquid. Sole at most we meet like, agaragar temperature, paint, starch, protein, gold sole, brimstone sole, glue and mud. Hal.: 13 Isi dengan Judul Halaman Terkait

Continuation H. Last colloid type is colloid having its(the dispersed phase and pendispersi medium solid matter, this colloid type called as with solid sole. Example of solid sole is; rock is having colour, glass is having colour, soil;land;ground, bronze, brass etc.. Hal.: 14 Isi dengan Judul Halaman Terkait

Tabel 11.2 Kinds Colloid Hal.: 15 Isi dengan Judul Halaman Terkait

Colloid Character Based on particle size from specific dispersed phase and medium pendispersi which is immeasurable, hence colloid has some main that is : 1. Colloid system menunjukan existence of Brownian movement that is not regular movement ( zig-zag) from partikelpartikel colloid, movement observed by Robert Brown. This movement happened continually effect [of] uneven hammering between colloid media with colloid particle. Brownian Motion can stabilize colloid system or prevents the happening of precipitation. This movement can only be seen by using microscope Hal.: 16 Isi dengan Judul Halaman Terkait

Continuation 3. coagulation of Colloid is gathering and cloting of partikelpartikel colloid. Event of coagulation happened at life of clay or mud is coagulation caused by sea-water electrolyte. Coagulation process from rubber also happened caused by addition of acid formiat kadalam latex. And so do the things of with colloid mud can be coagulation with alum loading. Hal.: 20 Isi dengan Judul Halaman Terkait

Picture 11.7 Adsorbsi ion by colloid Isi dengan Judul Halaman Terkait
Continuation 4. Colloid system also has energy?power adsorbsi strong to draw neutral ion or electrical charge and molecule. This thing is caused by colloid particle to have a real surface wide. For example water absorption process by chalk, sole Fe(OH)₃ in water contains ion Fe³⁺ diadsorbsi. While for the things haves negative charge is molecule As₂S₃, ion S²⁻] diadsorbsi. Exploiting of character adsorbsi from colloid for example in water depurating, for example usage of alum to tie dirt or dye from soil;land;ground ( Picture 11.7) Picture 11.7 Adsorbsi ion by colloid Hal.: 21 Isi dengan Judul Halaman Terkait

Picture 11.8 Loading colloid system Isi dengan Judul Halaman Terkait
Continuation 5. Loading colloid system can be pulled by electrode flown by concurrent electric current. For colloid which haves negative charge moving towards anode that is positive electrode and colloid which haves positif charge moving towards negative cathode or electrode Picture 11.8 Loading colloid system Hal.: 22 Isi dengan Judul Halaman Terkait

Colloid System Based on dispersion phase particle particle affinity to dispersion medium, hence there are two kinds of colloid system: A. Colloid Liofil ( likes dilution) : it is colloid having attractive force to draw strong between particle particles is dispersion with medium pendispersi. Medium pendispersi in liofil often is called as also with hidrofil. Colloid particle also mengadsorbsi dilution molecule can so that is formed mask is around [by] colloid particle. Existence of this mask causes colloid liofil is more stable. Hal.: 23 Isi dengan Judul Halaman Terkait

Continuation B. Liophobic colloid ( dilution fear): it is colloid having weak interesting attractive force between Partikel particle is dispersion with medium dispersi. Its(the dispersion medium is often is called as with hydrophobe. colloid particle haves no adsorbsi its(the solvent so that this colloid less stably and earns easily is coagulation with addition of electrolyte Hal.: 24 Isi dengan Judul Halaman Terkait

Continuation C. Protecting colloid is colloid which can covert of other colloid in order not to be coagulation. Interesting example is addition of colloid liofil into IYophobe, where prepacked IYophobic colloid doesn't gather, like making of Iump ice-cream in order not to be added gelatine. And so do the things of with paint and inking has protecting colloid in order not to tuang or Iump. Hal.: 25 Isi dengan Judul Halaman Terkait

This technique applied to make metal cell, metal which will be changed into form of colloid in putting down as electrode in dispersion medium and flown by electric current. Metal atom atom will be broken and come into dispersion medium. Picture Bow Technique Bredig Hal.: 32 Isi dengan Judul Halaman Terkait

Dissociation Of Colloid
dissociation of colloid : a. Dialysis is purification of dispersion medium from electrolyte, by the way of screening of colloid by using parchment paper or membrane placed is underwater ness is flowing. Beginning - colloid beginning packed into sack;bag having membrane semipermiabel then is packed into water so that interfering ion to pierce medium sack;bag of colloid particle constantly within sack;bag. Picture Dialisis Hal.: 33 Isi dengan Judul Halaman Terkait

Continuation b. Electrophoresis: colloid separation process loading with help of electric current. Partikel which are positive would towards cathode and negative would towards anode. Hal.: 34 Isi dengan Judul Halaman Terkait

Picture 11.13 association colloid
Soap and detergent is association colloid with water, where soap or detergent has two bunchs having the character of polar ( part of head) and non polar ( part of tail) pays attention to Gambar Part of head is polar group having the character of hidrofil ( likes water) and part of tail is hydrophobic group ( water fear). If soap dissolves in water, soap molecule will associate, bunch nonpolar interaction can with dirt ( haves the character of nonpolar) later on is dispersion into water.
