Second Semester: Analytical Chemistry Flashcards
What is Analytical Chemistry?
Branch of Chemistry dealing with the chemical characterization (qualitative and quantitative) of matter.
What is Qualitative Analysis?
Determination of what is present in a sample.
What is Quantitative Analysis?
Determination of how much is present in a sample.
Chemical analyses can be selective or specific. What is selective analysis?
It is the analysis that can occur with other substances but exhibits a degree of preference for the substance of interest or analyte?
Chemical analyses can be selective or specific. What is specific analysis.
It is the analysis that can occur only for the substance of interest or analyte.
Explain the Chemical System using an egg analysis.
The egg yolk represents the analyte or the specie of special interest. The egg whites represent the matrix or the part of the sample outside the analyte.
What are the applications and importance of analytical chemistry.
Agriculture, Forensic, Environment, Medicine, Geology, Fisheries, Industry, Organic and Inorganic Chemistry, Quality Control, Environmental Monitoring, Clinical and Biological Assays, Geological Studies, Fundamental and Applied Research.
Analytical Methods are performed either through wet-analysis or instrumental methods. What is wet-analysis.
Wet-analysis usually employs reciitation, titrimetric and gravimetric methods
What are instrumental methods.
uses sophisticated instruments capable of measuring the analyte’s physical and chemical properties.
Samples can either be destructive or non-destructive analysis. What is destructive analysis.
