A characteristic characteristic that distinguishes colloidal systems with solutions is by Tyndall experiments. When a solution is irradiated with a beam of visible light then the beam is absorbed and only a small part is emitted. When a beam of light is passed to the colloidal system then the ray will be transmitted by colloid particles, so that the light through the colloidal system will be observed as a light path.
This characteristic colloid is called by the name of Tyndall effect. In addition to colloid type of sol, Tyndall effect can also be seen in colloid type aerosol. In everyday life, the Tyndall effect can be seen in the event of the projector's light beam clearly visible in the cinema building that has a lot of cigarette smoke, and so on
.
1. Tyndall effect is a process of scattering light by colloidal particles
Examples in everyday life:
A. The occurrence of red and orange in the sky in the morning or afternoon and the occurrence of blue in the sky at noon
B. Highlight car or motorcycle lights when the air is foggy look more clear
C. Highlight the projector lamp in the cinema will be obvious when there is cigarette smoke. This results in the movie image on the screen being blurred
2. Brownian motion is a random motion of colloid particles, due to collisions with particles of the dispersing medium
Example: pollen in water using ultra microscope
3. Adsorption is the process of absorption of ions or microorganisms by the surface of colloidal particles, causing colloidal particles to be electrically charged.
Example:
A. The process of separating metal minerals from the ore in the metal industry
B. Purification of sugar cane in the process of making sugar using diatomaceous soil and bone char
C. The healing process of abdominal pain due to pathogenic bacteria using noritic or carbon powder
D. Purification of water with alum in drinking water treatment process
4. Electrophoresis is the process of moving colloidal particles due to the influence of electric fields.
Example: electrophoresis events are often used by the police in identifying the bodies of murder victims or unidentified bodies through DNA testing.
5. Coagulation is a clumping of colloidal particles by heating or by ion opposite the charge.
Example:
A. Clumping of mud or clay in the water purification process using alum
B. The process of forming the delta in the estuary, koagulannya sea water which is the electrolyte
C. Clump dust or factory smoke with electric coagulation devices (Cottrell sedimentation)
6. Dialysis is a way of reducing the disruptive ions present in the colloidal system by using a semipermiabel membrane.
Example: the process of dialysis for patients with renal failure (hemodialysis)
7. Colloid Protector is a Colloid that can protect other colloids to avoid coagulation
Example:
A. Gelatin, a protective colloid that prevents the formation of ice crystals in ice cream
B. Casein in milk can protect the fat or oil in a liquid medium, the protective colloid emulsion called emulgator
C. Lecithin, is a protective colloid that stabilizes the fine granules of water within the margarine
8. Colloid Liofil and Liofob
The lyophil sol is a sole whose dispersed phase has a great affinity in attracting its dispersing medium
The lyophob sole is a sole whose dispersed phase has a small affinity to the dispersing medium
Difference between lyophil sol and lyophob sole
Colloid Lycophino Lycophino Lycophyte
Adsorbs the medium.
Examples: glue kanji, gelatin.
Stable
Difficult to precipitate.
The Tyndall effect is less clear
More thick than the medium. Not adsorbing the medium.
Example: sol Fe (OH) 3, sulfur sol.
Less stable
Easy to precipitate
The Tyndall effect is clear
The viscosity is almost the same as the medium
What is the purpose and function in make rpp. Give me an example and explain
BalasHapusThe purpose of RPP (learning implementation plan) is to:
Hapus(1) facilitate, accelerate and improve teaching learning process outcomes;
(2) by developing a professional, systematic and efficient learning plan, the teacher will be able to see, observe, analyze, and predict the learning program as a logical and planned framework.
Meanwhile, the function of RPP (learning implementation plan) is as a reference for teachers to carry out teaching and learning activities (learning activities) to be more directed and run effectively and efficiently. In other words, the implementation plan of learning acts as the scenario of the learning process.
What are your indicator will be work? Cause i think that you have alot of indicator..
BalasHapusI will try and keep trying to get my indicator working properly.

HapusGive your opinion about rpp K13 with rpp ktsp and which one is better to use?
BalasHapusCurriculum 2013
HapusGraduate Competency Standards (SKL) is determined first and then the new Content Standards in the form of the Basic Curriculum Framework. The graduation competency aspect is balanced between soft skills and hard skills. The Integrated Integrated Primary School class I - IV. The lesson hours per week are more and the number of subjects is more A little bit compared to KTSP learning in elementary school (theme) and SMP / SMA / SMK (subjects) is done with a scientific approach. TIK is not a subject but a learning medium.Standard assessment uses authentic assessment, measuring all competencies.Pramuka so extracurricular mandatory.Programming started class X at SMA / MA.BK level is emphasized to develop student's potential.
Education Unit Level Curriculum (KTSP)
Standard Content is determined first and then determined SKL.Lebih emphasize to the knowledge aspect.Jematary Elementary School for class I - III.Jam less subjects and the number of subjects more than the Curriculum 2013.Standard learning process that is Exploration, Elaboration, and Confirmation. ICT so the subjects. Assessment is done in the aspect of knowledge.Pramuka not be extracurricular mandatory. Starting class XI jurusan SMA / MA.BK more on solving student problems.
On learning titled "Colloidal Properties", do you need a lab to apply the lessons you have made based on the RPP?
BalasHapusOf course we are in dire need of a laboratory at the time of study titled "Colloidal Nature", to apply the lessons that have been made based on the RPP.
HapusKKM has been determined, after complete assessment by teachers, students
BalasHapusCan answer well But why when UUB students can not afford
Answered?
With the learning plan, what percentage of students can understand the lesson .. ??
BalasHapusCan not be determined yet, but we must be and can make students interested in this method.
HapusExplain what you think is colloid Liofil and lyophobic colloid ?
BalasHapusColloid lyophil and colloid liofobmerupakan colloidal type of sole. Based on the adsorption properties of the sol are distinguished on solliophils and lyophob soles. The lyophil or lyophil lyoloid sole is a colloid type whose dispersed phase may bind or attract the dispersing medium.
HapusHow do you think about rpp, is it really helpful in the learning process ??
BalasHapus1. RPP is a proof of activities to be implemented by teachers in the classroom and must be prepared by teachers
Hapus2. RPP is a guideline to be used as teacher guidance in carrying out activities in class
3. By preparing the lesson plans, teachers have earlier thought of the best and easiest way to build the required competencies in the students so that students achieve these competencies.
4. By preparing the teacher's RPP as early as possible to estimate the effectiveness of classroom management both in terms of time, the creation of classroom atmosphere, as well as efforts to achieve learning objectives. So RPP is very important.
Whether there is an easy way to understand the nature of colloid with practice or other ?
BalasHapuswhat's importand design experiment?
