Ch-18: Qualitative Analysis

 Ch-18: Qualitative Analysis 

MCQs - Class 9 Chemistry Federal Board

In Unit 18, Qualitative Analysis, Class 9 Federal Board students learn how chemical tests can help identify substances in a sample. The chapter focuses on detecting gases using their characteristic test results and identifying certain metal cations by observing the colours they produce in a flame test. Students review the purpose of each test, the observations to look for, and how those observations help indicate which substance may be present. Use the chapter’s MCQs and short-question answers to revise gas detection and flame-test identification.
