LESSON PURPOSE
B. Establishing Purpose of the Lesson 2. Unlocking Content Vocabulary: Match Type Activity Soluble Insoluble Solvent -is one that can be dissolved in a particular solvent. - is one that cannot be dissolved in a particular solvent. -is the substance that dissolves the solute to form a solution. Solute -the substance that is dissolved in a solution.
C. Developing and Deepening Understanding Solute: The solute is the substance that is dissolved in a solution. It is the component that is present in a smaller quantity compared to the solvent. Examples of solutes include salt, sugar, and various minerals or compounds. Differentiating Solute and Solvent
C. Developing and Deepening Understanding Solvent The solvent is the substance that dissolves the solute to form a solution. It is the component that is present in a larger quantity compared to the solute. Water is a common solvent, but other substances like alcohol and acetone can also act as solvents. Differentiating Solute and Solvent
C. Developing and Deepening Understanding The roles of solute and solvent in forming a solution are as follows: Dissolution: The solvent dissolves the solute, breaking it down into smaller particles or molecules. This process of dissolution results in a homogeneous mixture, where the solute is evenly distributed throughout the solvent. The Roles of Solute and Solvent
C. Developing and Deepening Understanding The roles of solute and solvent in forming a solution are as follows: Concentration: The relative amounts of solute and solvent determine the concentration of the solution. The more solute that is dissolved in a given amount of solvent, the higher the concentration of the solution. The Roles of Solute and Solvent
C. Developing and Deepening Understanding The roles of solute and solvent in forming a solution are as follows: Homogeneity: A solution is a homogeneous mixture, meaning it has the same composition and properties throughout. The solute is evenly dispersed and integrated into the solvent, creating a uniform substance. The Roles of Solute and Solvent
