4. Pencampuran air dan minyak goreng
Air dan minyak goreng tidak tercampur. Kedudukan minyak goreng di permukaan air.
5. Pencampuran air, minyak goreng, dengan air sabun
Minyak goreng dapat tercampur rata dalam air.

VII. Analisis Data :
Pembuatan sol belerang menggunakan cara dispersi (mekanik) yaitu dengan menggerus serbuk belerang dan ditambahkan gerusan zat inert yaitu gula pasir agar belerang dapat tenggelam dalam air. Belerang yang telah dihaluskan bersama gula akan membentuk butiran yang ukurannya menyerupai koloid. Kemudian campuran dilarutkan dalam air sehingga menghasilkan koloid jenis sol.
Untuk pembuatan agar-agar digunakan cara peptisasi. Cara peptiasi ini menggunakan zat pemeptiasi (pemecah) yaitu air dengan dipanaskan untuk memecah molekul-molekul besar dalam hal ini serbuk agar-agar supaya menjadi molekul-molekul kecil ukuran koloid. Setelah air dan agar-agar sudah menyatu sepenuhnya kemudian didinginkan sejenak. Maka jadilah sol padat yaitu agar-agar.
Proses pembuatan sol Fe(OH)3 dengan cara kondensasi yang dilakukan melalui reaksi hidrolisis. Reaksi hidrolisis merupakan suatu reaksi garam dengan air. Cara kondensasi itu sendiri bekerja dengan menggabungkan ion-ion dari larutan sejati sehingga membentuk partikel yang lebih besar seperti ukuran partikel koloid (1-100 nm). Reaksi tersebut sudah berlangsung ketika sudah terjadi perubahan warna campuran yang semula merah bata menjadi berwarna coklat kemerahan.
Minyak dan air adalah emulsi (cair bertemu cair namun bersifat antagonis/ tolak – menolak) sehingga tidak bisa larut dalam air. Kedudukan minyak berada di permukaan air, hal ini disebabkan oleh massa jenis minyak yang lebih kecil dari pada massa jenis air.
Agar minyak larut dalam air maka ditambahkan emulgator yaitu larutan sabun. Kemudian air dan minyak tersebut dapat bercampur. Sabun disebut sebagai emulgator karena dapat menggabungkan dua buah fese yang tidak bisa bersatu.

The making of sol gelatin in waterAfter cooled or left for a moment, into a solid gel like and the colour is green3. The making of sol Fe (OH) 3 in waterMix boiling water with FeCl3 into greater thick and Fe (OH) 3 the colour is reddish brown4. Mixing of water and cooking oilWater and cooking oil are not mixed. The position of cooking oil on the surface of the water.5. Mixing of water, cooking oil, SOAP and waterCooking oil can be well mixed in water. Vii. Data Analysis:The manufacture of sulfur sol use the dispersion (mechanical) with sulfur powder and erode added inert substances namely gerusan granulated sugar so that the sulfur can be immersed in water. Sulfur that has been mashed together to form sugar granules whose size resembling a colloid. Then the mixture is dissolved in water to produce the kind of colloidal sol.For the manufacture of gelatin used peptisasi way. How to peptiasi use pemeptiasi substances (solvers) that is heated with water to break up the large molecules in this case so that the gelatin powder into molecules small colloidal size. After the water and gelatin are already fused completely and then cooled down for a moment. Then be dense namely gelatin.The making of sol Fe (OH) 3 in a way that is done through the condensation reaction of hydrolysis. Hydrolysis reaction is a reaction of the salt with water. The way the condensation itself works by combining ions from aqueous solutions of true forming larger particles such as colloidal particle size (1-100 nm). The reaction is already underway when this has happened the changing colours of the original red brick mixture becomes reddish brown.Oil and water emulsion is (liquid liquid met yet are antagonists/reject – refuse) so can not dissolve in water. The position of the oil is on the surface of the water, this is caused by the mass of the type of oil that is smaller than the density of water. In order for water soluble oils then added emulgator i.e. a solution of SOAP. Then the water and oil mixed. Emulgator is referred to as SOAP because it can combine the two pieces of the fese don't mix.VIII.

III. How it Works:
A. Making the sol by means disperse
Sol sulfur in the water:
1. Mixing a dose of sugar and one dose of sulfur in a mortar. Grind the mixture until smooth.
2. Take one dose of the mixture and mix again with a single dose of sugar, then grind again until smooth.
3. Continuing the work is up to 4 times, then fill it with 50 ml of water. Stirring the mixture and watched what happened.
Sol that - that in the water:
1. Taking one spatula order - order and dissolving in water as much as a third of the reaction tube.
2. Then, to facilitate dissolution, then the mixture is heated. Then observe what happens.
B. Making the sol by means of condensation
Sol Fe (OH) 3:
1. Heats 50 ml of water in a 100 ml beaker to boil.
2. Add 25 drops of saturated FeCl3 solution, and stirring while continuing the heating until the solution red-brown. Then observe what happens.
C. Manufacture of Emulsion
1. Insert 1 ml of cooking oil and 5 ml of water into a test tube. Shake the test tube with a bang. Putting the tube in the test tube rack and pay attention to what happens.
2. Add 25 drops of soap solution. Shake the test tube with a bang. Then put the tube in a rack and watched what happened. Then, the result of the mixing of the colloidal type of emulsion VI. Observations: No Experiments Observations 1. Making the soles of sulfur in the water Forms cloudy white mixture and after a rather long left no sediment on the bottom of the mixture 2. Making the sol gelatin in water After cooled or allowed for a moment, became solid like gel and green color 3. Making the sol Fe (OH) 3 in water mixture to the boiling water into lebuh thick FeCl3 and Fe (OH) 3 reddish brown color 4. Mixing water and cooking oil Water and oil do not mix. Position the cooking oil on the water surface. 5. Mixing water, cooking oil, soapy water Cooking oil can be blended in water. VII. Data Analysis: Making use of sulfur sol dispersion method (mechanical) is to grind sulfur powder and added scour inert substance that is sugar so that the sulfur can be submerged in water. Sulfur that has been mashed together with the sugar to form granules that resemble colloid size. Then the mixture is dissolved in water to produce a colloidal sol types. For the manufacture of gelatin used peptizing way. How to use substances peptiasi pemeptiasi (solvers) that the water is heated to break down large molecules in this case powdered gelatin molecules to become small size colloids. After the water and the gelatin has completely fused and then cooled momentarily. Therefore be solid sol is gelatin. The process of making sol Fe (OH) 3 by means of condensation is done through the hydrolysis reaction. The hydrolysis reaction is a reaction of salt with water. How to condensation itself works by combining ions from the true solution so as to form larger particles such as colloidal particle size (1-100 nm). The reaction is already in progress when it changes the original color of red brick mixture becomes reddish brown. Oil and water are emulsified (liquid molten met but antagonistic / reject - reject) so it can not dissolve in water. Position the oil is on the surface of the water, this is caused by the density of the oil is less than the density of water. For water-soluble oil, the emulsifier is added to a solution of soap. Then the water and the oil can be mixed. Soap referred to as emulsifier because it can combine the two fese that can not be united. VIII. Questions and Answers: a. Question: 1. What is the difference of making sol dispersion method by means of condensation? 2. How does the soap solution to the mixture of water with cooking oil? 3. Give each - each two examples include colloidal liofil and liofob! 4. In the hydrophilic colloid is necessary to add a protective colloid. What are the benefits of the addition of the colloid? 5. Of share ways of making the colloidal dispersion and condensation, grouped the way - the way into a group that includes the physical processes and chemical processes! 6. Explain the manufacture of colloid in a way peptizing! 7. Mention how to manufacture sulfur sol including ways and means of dispersion condensation!
