Mixtures & Solutions
Learning Outcomes1. Discuss the technological applications of mixing substances to produce new materials.
2. Classify substances as pure substances or mixtures based on observations of the properties of the substances. 3. Identify the characteristics of a solution. 4. Design and conduct an experiment to determine the solubility of two different substances, then evaluate the limitations of the design. 5. Use knowledge of the properties of substances to separate the components in a mixture. 6. Design and conduct an experiment to compare the effectiveness of different solvents at removing a variety of stains, then discuss the limitations of the experimental design. 7. Apply chromatography to perform a comparative analysis of solutions. ActivitiesComplete online lesson 5: Classifying Chemicals using Properties.
