Name: _____________________________________________ Date: ___________Period:__________ A Created by Jen Solari Experimenting with Solutions – Designing an Experiment A Solution is a type of homogeneous mixture formed when one substance dissolves in another. The particles of the mixing substances are evenly spread throughout. The substance that is dissolved is called the solute . The substance that does the dissolving is called the solvent . If a substance is soluble in water, it means the substance can dissolve in water. The amount of solute that will dissolve in 100 grams of water is called the solubility . Solubility is effected by temperature. The solubility of a substance is a characteristic property of the substance. When one substance is dissolved in another a physical change has taken place. In this activity you will: 1. conduct research to find the three factors that affect the rate at which a solute dissolves in a solvent. 2. design an experiment to test the effect of one of these factors on the rate at which salt or sugar crystals dissolve in water. 3. identify the parts of the experiment by completing an EDD. 4. create an appropriate data table that includes space for all variable levels and trials. You also need to include an appropriate title (one that describes the data being collected) and units of measurement. Problem Question:
