EVERYDAY SCIENCE

Detailed explanation-1: -qualitative chemical analysis, branch of chemistry that deals with the identification of elements or grouping of elements present in a sample. The techniques employed in qualitative analysis vary in complexity, depending on the nature of the sample.

Detailed explanation-2: -In qualitative analysis, the ions in a mixture are separated by selective precipitation. Selective precipitation involves the addition of a carefully selected reagent to an aqueous mixture of ions, resulting in the precipitation of one or more of the ions, while leaving the rest in solution.

Detailed explanation-3: -Qualitative analysis tells ‘what’ is in a sample, while quantitative analysis is used to tell ‘how much’ is in a sample. The two types of analysis are often used together and are considered examples of analytical chemistry.

Detailed explanation-4: -What Is Qualitative Analysis? In business and management, qualitative analysis uses subjective judgment to analyze a company’s value or prospects based on non-quantifiable information, such as management expertise, industry cycles, strength of research and development, and labor relations.

Detailed explanation-5: -Qualitative analysis is the study of hypothetical and ambiguous information that can be difficult to collect and measure. It tends to be inductive rather than deductive, and it is non-numerical data-this type of data is usually analyzed by setting relevant hypotheses.
