Explain why the differentiating characteristic is at the heart of achieving each of the four goals of quantitation, detection, identification, and separation when the sample is a mixtuie of many compounds.
Homework Answers
When the sample is a mixture of many compounds, it is obvious that its characteristics will be different from that of the virgin compound.
Quantitation study will leads to the fact that the mass of the product (sample) which is a mixture of many compound should neccesarily different (either less/more) than that of original compound.
Detection and identification study will reveal the change of any characteristics of the original compounds after their mixing e,g. in case of organic compounds, the peaks obtained for the product in IR spectroscopy should have some difference than that of the original compound. Identification of the peaks will result in differentiation of the product from the reactants.
Separation is necessary because it will lead to removal of unreacted components from the products, thus achieving pure compounds. Various separating methods are available such as filtration, evaporation, distillation, chromatography etc.
