QUARTER 1 WEEK 2 DAY 1 REVIEW Directions: Identify whether the mixture is homogenous or heterogenous mixture. 1.Saltwater 2. Sugar solution 3. Air REVIEW 4. Salad 5. Granite  What drinks do you usually prepare during breakfast? Have you not wondered which of those substances does the dissolving or the substance that is being dissolved? Differentiating a Solute form a Solvent SOLUTION When one substance dissolves into another, a solution is formed. A solution is a homogenous mixture consisting of a solute dissolved into a solvent. SOLVENT A solvent is a substance that does the dissolving or it is a substance used to dissolve a solute. It is of a larger amount. A solute dissolve or the substance that is being dissolved, it is of smallest amount. SOLVENT Water is called the universal solvent because it dissolves more substances than any other. There are solutes that can be dissolved in solvent, it is called soluble. SOLUBLE Table salt, sugar, instant coffee, vinegar, and aspirin are soluble in water, forming solutions when mixed due to their ability to dissolve and create homogeneous mixtures. INSOLUBLE However, there also substances that cannot be dissolved in solvent, it is called insoluble. Insoluble objects like sand, oil, metal nails, wood, and plastic do not dissolve in water and maintain their distinct properties when added to it. ACTIVIT Y 1 Directions: Write TRUE if the statement is correct, FALSE if not. 1. A solution is formed when one substance dissolves into another, resulting in a homogeneous mixture. ACTIVIT Y 1 2. In a solution, the solute is the substance that is being dissolved, while the solvent is the substance that does the dissolving. 3. Water is often referred to as the universal solvent because it can dissolve a wide variety of substances. ACTIVIT Y 1 4. Soluble substances can be dissolved in a solvent to create a solution. 5. Insoluble objects like sand, oil, metal nails, wood, and plastic do not dissolve in water and maintain their separate properties. ASSESSMENT Directions: Complete the Venn diagram by identifying the difference between a solute and a solvent. characteristics characteristics of a solute similarities of a solvent QUARTER 1 WEEK 2 DAY 2 REVIEW Directions: Complete the statements below by choosing the correct answers from the given choices in the box.

Insoluble objects like sand, oil, metal nails, wood, and plastic do not dissolve in water and maintain their distinct properties when added to it. ACTIVIT Y 2 Directions: Draw a if the statement is correct, if not. 1. Vinegar contains acetic acid and is soluble in water, forming a solution. 2. Instant coffee granules are soluble in hot water, creating a cup of coffee when stirred. ACTIVIT Y 2 3. A solvent is typically present in a larger amount than the solute within a solution. 4. When a solute dissolves in a solvent, its distinct properties become less noticeable in the resulting solution. ACTIVIT Y 2 5.

Based on the given illustration, which is the solute? Which is the solvent? REVIEW Directions: Answer the following questions below. 2. How is the solute being dissolved in the given solvent? Try to unscramble them to reveal the original words related to solubility and solutions! 1. STRIRING 2. EMERTUETAPR 3. VOTLENS 4. TULSOE 5. OTISNUOL  FACTORS AFFECTING SOLUBILITY SOLUBILITY Solubility is the maximum amount of a solute substance that will dissolve in a given amount of solvent at a specific temperature. There are different factors that affect solubility: SOLUBILITY → Nature of solute and solvent → Temperature of solvent → Manner of stirring → Amount of solvent → Size of the solute SOLUBILITY The Effect of Nature of Solute and Solvent on Solubility: Solubility of a solute in a solvent depends on the nature of both solute and solvent. SOLUBILITY Example: salt-(solute) dissolves in water- (solvent) nail polish dissolves in acetone We cannot dissolve nail polish in water but water can dissolve salt. SOLUBILITY The Effect of Temperature of Solvent on Solubility Temperature affects the solubility of a solution. Raising the temperature will increase the solubility of a solute in a solvent. SOLUBILITY Example: A hot water dissolves a medicine easily than cold water. SOLUBILITY The Effect of Manner of Stirring on Solubility Stirring affects how quickly a solute dissolves in a solvent. In the absence of stirring, the concentration of solute will be highest close to the pieces of solute, so more solute won't dissolve into the solution until it is stirred. SOLUBILITY The solute will dissolve faster by diffusion. One important concept of solution is in defining how much solute is dissolved in a given amount of solvent. This called concentration. SOLUBILITY If the solution has small amount of solute it describes as a Dilute while concentrated describes solution that has a lot of solute in each solvent. There is only a certain maximum amount of solute can be dissolved in a given solvent. This maximum amount is called the solubility. ACTIVIT Y 4 Directions: Complete the following by choosing the correct word inside the parenthesis to complete the sentence. Write your answer using your Science journal or notebook. ACTIVIT Y 4 1. Solubility is (increasing or decreasing) as temperature is rising. 2. Solubility is (increasing or decreasing) as temperature is decreasing. ACTIVIT Y 4 3. Which substance is more soluble, sugar or flour? Why? ___________________________________ 4. What will be the most effective means of increasing the dissolving rate of sugar in water? ________________________ ACTIVIT Y 4 5. Which solvent dissolves the sugar most quickly? water alcohol mineral oil. Explain your answer. ___________________________________ ASSESSMENT Directions: Read the sentences carefully. Identify the factors that affect solubility for each sentence. Choose your answer inside the box. A. TEMPERATURE B.MANNER OF STIRRING C.NATURE OF SOLUTE D.AMOUNT OF SOLVENT E.SIZE OF SOLUTE ASSESSMENT 1. When the solution is heated, more solute will dissolve in the solvent. 2. Gasoline does not dissolve in water, does decreasing the solubility of gasoline. ASSESSMENT 3. When 2 tablespoons of sugar are added to 200ml of water, more sugar particles are dissolved as compared when the same amount of sugar is dissolved in 50ml of water. ASSESSMENT 4. Before using a suspension medicine, the label instructs you to shake it well before using it so as to dissolve the solute particles in the suspension. 5. More fine salts dissolve in water as compared to table salt mixed in water. QUARTER 1 WEEK 2 DAY 4 REVIEW Directions: In the given situation, identify what factors affect the solubility of the following materials. Choose your answer inside the box and write your answer on your notebook. REVIEW A. TEMPERATURE B.MANNER OF STIRRING C.NATURE OF SOLUTE D.AMOUNT OF SOLVENT E.SIZE OF SOLUTE REVIEW 1. It tells about whether the solvent is in liquid, solid or in gas form. 2. It depends on how fast or slow mixture was stirred. REVIEW 3. It tells whether the solute is soft or hard, powder or a whole piece. 4. It tells how hot or cold is the solvent mixed in a mixture. 5. It tells how much solvent is mixed in a mixture. How does temperature affect the solubility of a mixture?  FACTORS AFFECTING SOLUBILITY SOLUBILITY Solubility is the maximum amount of a solute substance that will dissolve in a given amount of solvent at a specific temperature.
