EVERYDAY SCIENCE

Detailed explanation-1: -Perhaps the most common analytical problem is a quantitative analysis, examples of which include the elemental analysis of a newly synthesized compound, measuring the concentration of glucose in blood, or determining the difference between the bulk and the surface concentrations of Cr in steel.

Detailed explanation-2: -Quantitative analysis is any method used for determining the amount of a chemical in a sample. The amount is always expressed as a number with appropriate units. An acid-base titration is an example of quantitative analysis.

Detailed explanation-3: -In chemistry, the distinction between qualitative and quantitative analysis is that qualitative analysis determines the presence or absence of various chemical components in a sample, whereas quantitative analysis determines the amount of various chemical components present in a sample.

Detailed explanation-4: -Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (Medwick and Kirschner, 2010). Since volume measurements play a key role in titration, it is also known as volumetric analysis.

Detailed explanation-5: -Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass.
