Unit 10
In unit 10 of chemistry we will explore solution formation. We begin the unit by looking at the dissolving properties of water. Solute, solvent, and solution formation will be explored using a variety of mediums. Students will then explore the relationship between bonding and conductivity. Next, students will look at the relationship between temperature and solubility through lab. Then students will be asked to determine the strength of solutions mathematically using molarity, molality, percent solution, and dilution calculations. This will be done by dissecting soda and finding the amount of carbon dioxide and sugar within a given solution. We will also dissect margarine to find the percent of water in regular vs. lite. The final concept we will explore is freezing and boiling point changes of solutions. We will make root beer floats and examine how regular vs. diet soda interacts with the ice cream.
