LEARNING ACTIVITY SHEET Homogeneous and Heterogeneous Mixtures

Background Information for Learners (BIL) A mixture is made up of two or more substances that are combined physically. The substances in the mixture are observable and can be identified easily because they retain their own composition and properties and can be easily separated through physical means. A mixture can be formed by mixing solid with other solid, liquid with other liquid and solid with liquid. Mixture can be classified as homogeneous (uniform) mixture and heterogeneous (non-uniform) mixture. Homogeneous mixture is also called a solution since its composition is uniform all throughout and is seen in a single phase. On the other hand, a heterogeneous mixture does not have uniform composition thus the individual substances can be identified or remain distinct.

Learning Competency: Describe the appearance and uses of homogeneous and heterogeneous mixtures. (S6MTIa-c1) • • •

LEARNING ACTIVITY SHEET Differentiating Solutes from Solvents

Background Information for Learners When a substance is completely dissolved in another substance, it forms a homogeneous mixture called solution. A solution has two important components: solute and solvent. A solute is the substance that is dissolved and usually present in a smaller amount. On the other hand, a solvent is the substance in which a solute dissolve, usually liquid and is present in a greater amount. Water is an example of a liquid solvent. It is also known as universal solvent because it dissolves different kinds of substances. An example of solute that dissolves in water is sugar. When sugar is mixed with water, the dissolved particles are not distinguished from the water. Substances that are completely dissolved in solvent are called soluble substances. There are solutes that do not completely dissolved in a solvent. These are called semi-soluble substances. Solutes which do not dissolve in any solvent are called insoluble substances.

LEARNING ACTIVITY SHEET Factors Affecting Rate of Solubility Background Information for Learners Solubility is the ability of a solute to dissolve in a solvent at a given temperature. Usually the higher the temperature, the faster a solute can be dissolved in a solvent. When a substance dissolves quickly and easily, it has high solubility. If it does not dissolve easily, it has low solubility. Rate of solubility is the measure of how fast a substance dissolves. There are different factors that affect the rate of solubility: 1. Nature of Solute and Solvent, 2. Temperature, 3. Manner of Stirring, 4. Amount of Solvent and 5. Size of the Solute. Solutions have different level of concentrations depending on the amount of solute dissolves in a solution. A solution with a little amount of solute is called diluted while a solution with a large amount of solute is called concentrated. Meanwhile, a solution that can no longer hold anymore solute at a given temperature is called saturated.

LEARNING ACTIVITY SHEET Suspension and Colloid and their Uses

Background Information for Learners (BIL) Suspension A Suspension is heterogeneous mixture of two substances in which one is dispersed into the other, suspensions involve particles larger than those found in solutions. The bigger particles of a suspension usually settle or separate out of a mixture upon standing or are able to be filtered out, although not through filter paper. Gravity is able to pull the visible particles in a suspension down if undisturbed, and they will stay that way unless being actively mixed. The ability of a liquid substance to mix with other liquid contributes on what kind of mixture is formed when substances are mixed. Immiscible liquids do not mix thoroughly with other liquids. One liquid may float and the other sink hence forming suspension. Common household suspensions are very important in our daily living. They have essential uses like enhancing the taste of the food and making our chores easier . Examples of suspensions include oil and water, dust or soot in air, sand and water and muddy water, paints, oil paints, milk of magnesia, some medicines, sand particles and water.

. Colloid

Colloid is a mixture that exhibits both properties of liquid and solid and it is called a non-uniform mixture because the particles do not settle but remain dispersed throughout the medium. The phase that is scattered or present in the form of colloidal particles is called dispersed phase and the medium in which the colloidal particles are dispersed is called the dispersion medium example starch solution, starch represents the dispersed phase while water represents the dispersion medium. Colloids can be in the form of sol, emulsion, aerosol, foam or gel.

Examples Solid sols: opal, pearl, colored glass Liquid Sols: blood, paint, muddy water milk, cod-liver oil, butter, mayonnaise clouds, fog, dusty air, insecticides, smoke perfume spray, spray paint Liquid foams: whipped cream, froth on glass of beer, soap lather Solid foams: polystyrene, pumice, yeast bread, cake icing shoe polish, gelatin, silica gel, jelly, jam

Common household colloids are rubbers, plastics, synthetic fibers, gelatin, and foams. They are used as thickening agents in industrial products such as lubricants, lotion, toothpaste, coatings, inks and etc.

LEARNING ACTIVITY SHEET Ways of Separating Components of Mixtures

Background Information for Learners Mixtures that are physically mixed can be separated through applicable ways. Knowledge and skills in separating them are important to be able to obtain the desired component or substance for us to better understand how each element contribute to the properties of a mixture. The different techniques of separating mixtures are very useful in our daily lives. Dry mixtures containing two or more components of different sizes can be separated through sieving. Undissolved solids in liquid can be separated by filtration which is a technique that causes the liquid part of the mixture to pass through a porous membrane such as a filter paper. Decantation is a technique of separating a less dense substance from a denser one. The less dense substance can be separated by scooping or removing slowly by pouring it out. Fats that float in your soup can be separated through decantation. Evaporation is used in separating mixtures through the application of heat. Salt crystals are separated from salt solution by evaporation. Mixtures containing both metals and nonmetals can be separated by using a magnet. Metals can be easily attracted by a magnet while nonmetals are not. Pins, needles, thumbtacks and iron filings are common examples that can be attracted by magnets. When these materials are mixed with nonmetals they can be separated by using a magnet

Learning Competency: Describe techniques in separating mixtures such as decantation, evaporation, filtration, sieving and using magnet. (S6MT-Id-f-2)

• • •

Identify the mixtures that can be separated through each technique Identify the processes of separating mixtures which uses each technique Use the technique in everyday life

Activity 1 - Got to Know ME A. Directions: Read each sentence carefully. Encircle the correct word from the parenthesis that describes each statement below. 1. This technique involves separating objects from a mixture which are made up of metals. (filtration, sieving, using a magnet, decantation, evaporation) 2. This technique is used if you want to separate salt crystals from salt water by drying it under the sun. (sieving, using a magnet, filtration, decantation, evaporation) 3. This technique involves separating solid particles from a liquid substance using a piece of cloth. (using a magnet, filtration, sieving, decantation, evaporation) 4. Materials made of iron mixed with other materials in a mixture can be separated using this method (using a magnet, sieving, filtration, decantation, evaporation) 5. This technique is used to separate bigger solid components from finer ones. (filtration, sieving, using a magnet, decantation, evaporation) 6. This technique separates solid substances with the use of a mess wire or screen. (sieving, using a magnet, filtration, decantation, evaporation) 7. This technique in which magnetically susceptible material is extracted from a mixture. (using a magnet, filtration, sieving, decantation, evaporation) 8. This technique is used to separate an insoluble solid that settles at the bottom of a liquid. (filtration, sieving, using a magnet, decantation, evaporation) 9. This technique is used in separating the components of two liquid mixtures that form two layers. (sieving, using a magnet, filtration, decantation, evaporation) 10. This technique is used to separate iron particles from the mixture. (using a magnet, filtration, sieving)
