Unit 3 Lab Solution Chemistry Unit 3: Solution Chemistry

Learning Objectives:  To learn how to prepare solutions of specific concentrations  To learn about molarity, and % concentration. In this lab, we will learn how to calculate solution concentration and prepare solutions. For a given solution, different ways of expressing concentration are used depending on our purposes. Solutions made of the same substances but at different concentrations can have very different properties. For example, an animal cell placed in a 0.1% NaCl solution will swell, the same cell placed in a 10% NaCl solution will shrivel or crenate. A good understanding of solution concentration is vital to the understanding of many natural and synthetic processes. Note to Students:  Read the lab before coming to class. The expectation at Chamberlain (CCN/CU) is that you come to class fully prepared for lab.  Always dress properly for lab. Be sure to wear closed toed shoes and long pants to lab. In lab, wear your safety equipment including goggles, lab coat, and gloves.  Always check with your instructor regarding proper waste disposal.  Listen carefully to the professor’s instructions and work safely.  Always follow the rules outlined in the safety contract.  If in doubt of how to use a piece of lab
