designing a qualitative study. This discussion does not replace the many excellent‚ detailed references on data collection (we refer to several at the end of this chapter). Its purpose is to guide the proposal writer in stipulating the methods of choice for his study and in describing for the reader how the data will inform his research questions. How the researcher plans to use these methods‚ however‚ depends on several considerations. Chapter 1 presents an introductory discussion of qualitative methodological

Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion
