Investigating the Determining Characteristics of Cations and Anions Chem 111 Sec 560 Introduction: The purpose of this lab was to study the specific characteristics of cations and anions‚ and ultimately to be able to identify an unknown substance based on our studies and tests using the logic trees developed through the experiment. A logic tree is a graphical display of the findings from this lab which‚ through a series of yes/no questions‚ elimination

percent yield of the experiment. Experiment and Observation: The first step in the experiment was to weigh 1g of CaCl2 +2 H2O‚ then pour it into the 100mL glass beaker with 25mL of distilled water and then stir it to make the solution calcium chloride. The next step was to calculate the amount of Na2CO3 I needed for it to completely react with the CaCl2 +2H2O using stoichiometry. 1.0g CaCl2+2H2O= 1mol CaCl2+2H2O =0.006802mol CaCl2+ 2H2O 147.0156g CaCl2+2H2O g

EXPERIMENT II: SEPERATION OF A MIXTURE OF SOLIDS PURPOSE: The purpose of this experiment was for me to become familiar with the separation of mixtures and solids and to learn separation techniques based on the chemical properties of a substance. PROCEDURE: Before beginning‚ I set up a data table to record data from the experiment. 1. Separating out the Iron a) I used my digital scale to determine the mass of my weighing dish. b) I emptied the entire mixture of solids from the plastic bag into

nucleophilicities of chloride and bromide ions toward the n-butyl and t-pentyl alcohols. We were able to analyze this by using refractometry to measure the amounts of alkyl chloride and alkyl bromide in each reaction. Experiment Scheme (Procedure A) To begin the experiment‚ we assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser. Next we added 44 mL of sulfuric acid to a 125 mL Erlenmeyer flask. We also measured 4.75g ammonium chloride and 8.75g ammonium
