Chem 11 Exp #2 Separation and Analysis of a Ternary Mixture Pre-lab Reading Assignment 1. Review Percent Composition of Compounds (page 58-60) and sublimation (page 808) in Zumdahl. 2. In a flowchart design, prepare a procedure to separate a mixture of solid sodium chloride (NaCl), ammonium chloride (NH 4 Cl), and silicon oxide (SiO 2 , sand), refer to Table 1. Introduction The goal of this laboratory experiment is to determine the percentage of each component in a mixture of solid sodium chloride (NaCl), ammonium chloride (NH 4 Cl), and silicon dioxide (SiO 2 , sand). Table 1 shows physical properties for each of the components in the ternary mixture. After assessing the physical properties of each substance in the mixture, each component's solubility and sublimation properties can be exploited using sublimation, evaporating or decanting techniques. Working with your lab partner and using your flowchart from the pre-lab assignment, establish a procedure for successfully separating and analyzing the mixture. Before beginning the actual experiment, discuss your
