Teacher: assalamualaikum, students are good materials today about Dispersion system. Here there are some solutions that are in front. First solution of sand solution (water + sand), second solution of salt solution (salt + water), third solution of coconut milk. Try you observe the solution. The solution is one example of some dispersed systems. Anyone knows some of the dispersed system division groups?

Kahf: bu, I do not know how many groups of distribution. Please explain the division and the details? Mom.

Zakka: yaa bu, my question is agree with your brother and please explain bu.

Teacher: based on the size of the particles, the disperse system is divided into 3 namely:

1. Suspense is a disperse system where the relatively large size of the patent
 is spreadevenly in the dispersing medium. in general, the disperse

 system is a heterogeneous mixture.Suspense has an

 unstable dispersive system so that if the solution 

 is not stirred continuously will settle due to the
 force of gravity of the earth.
2. The solution is a disperse system whose particle size is so small

that it can notbe distinguished (observed)between the dispersing

 particles and the dispersed particles, although using

a microscope with a high degree of enlargement.

3.colloid is a dispersed system with a larger particle

size than the solution, but smaller than  the suspense.
In general, the particle size is relatively small, 



the colloidal system can not be observed directly using the eye 
but using a microscope that is not accurate with the same  
same dilution From the example of this front-facing.
 example try the example analysis of each dispersion!
Zakka and kahf: well mam.
Kahf: So, Mam. Example from suspense: first solution
 (water + sand), colloid: third solution (coconut milk). 
Zakka: and the solution example is the second solution (water + salt).
Teacher: yes, right. Try looking for another example of 3 
dispersed systems with the tools already available.
 Zakka and kahf: well bu                                                                                                    
 Zakka: sample search system dispersed from suspense ie  gravel
solution (water + small pebbles), and sample of















solution ie sugar solution (water + sugar) 















Kahf: and the example of colloid is milk, glue. 
Teacher: yes, that's all 3 examples of dispersion system.
Zakka: mam, so the disperse system there are three  
groups namely, suspense, solution and colloid.
Kahfi: as well as the suspension solution, it



can be distinguished between solvent and solute, 











while the solution, can not distinguish between solute  
and solvent, then the colloid, between solution and 
suspense and can be distinguished particles using a 
 microscope. Yes ma'am.
Teacher: so that's the conclusion of the material today,  
and we end the meeting today. Enough so learn today
and mam end, wassalamualaikum warahmatullahi wabarakaatuh.
