Lab 13 Qualitative Analysis of Cations and Anions
AP Chemistry Lab #13 Page 1 of 8. Lab #13: Qualitative Analysis of Cations and Anions Objectives: 1. To understand the rationale and the procedure behind the separation for various Cations and Anions . 2. To perform Qualitative Analysis of two unknown solutions that contain various ions ( Cations and Anions ) and positively identify these ions using established schemes. Materials: Unknown Cation Solution (may contain some or all of the following) Unknown Anion Solution (may contain some or all of the following) M silver nitrate, AgNO3 (aq) M sodium chloride, NaCl (aq) M copper (II) nitrate, Cu(NO3)2 (aq) M sodium carbonate, Na2CO3 (aq) M zinc nitrate, Zn(NO3)2 (aq) M sodium sulfate, Na2SO4 (aq) M iron (III) nitrate, Fe(NO3)3 (aq) M sodium nitrate, NaNO3 (aq) 6 M HCl (aq) 18 Test Tubes and 4 Test Tube Racks 6 M HNO3 (aq) 400 mL Beaker (Waste) 6 M NH3 (aq) 250 mL Beaker 6 M H2SO4 (aq) Spatula 6 M NaOH (aq) 6 Beral-type Pipets 6 M CH3 COOH (aq) Hot Plate M KSCN (aq) Stirring Rods M potassium ferrocyanide solution, K4Fe(CN)6 (aq) 6 Small Test Tube Stoppers M AgNO3 (aq) Litmus or pH Paper Saturated Ba(OH)2 (aq) Watch Glass M BaCl2 (aq) Centrifuge Aluminum granules Background Information: Qualitative Analysis is an analytical procedure in which the question what is present?
