EVERYDAY SCIENCE

Detailed explanation-1: -Qualitative Analysis – reveals chemical identity of elements and compounds in a sample. – 2. Quantitative Analysis – determines the relative amounts of each substance in a sample.

Detailed explanation-2: -Qualitative analysis typically measures changes in color, melting point, odor, reactivity, radioactivity, boiling point, bubble production, and precipitation. Methods include distillation, extraction, precipitation, chromatography, and spectroscopy.

Detailed explanation-3: -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-4: -Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method.

Detailed explanation-5: -The component in the sample of interest to us is called the analyte, and the remainder of the sample is the matrix. In an analysis we determine the identity, the concentration, or the properties of an analyte. To make this determination we measure one or more of the analyte’s chemical or physical properties.
