ANALYTICAL CHEMISTRY EXAMINATION PREP
STUDY GUIDE LATEST UPDATED PRACTICE
SOLUTION VERIFIED 100 PERCENT
◉ Analytes. Answer: the components of a sample that are to be
determined
◉ Qualitative analysis. Answer: reveals the identity of the elements
and compounds in a sample
◉ Quantitative analysis. Answer: indicates the amount of each
substance in a sample
◉ Friedrich Wilhelm Ostwald. Answer: -winner of the *1909 Nobel
Prize in Chemistry*
-pioneer in the field of catalysis and one of the first chemists to
recognize the importance of thermodynamics
◉ Analytical Chemistry. Answer: art of recognizing different
substances and determining their constituents
◉ Chemistry. Answer: often termed as "central science"
◉ Quantitative analysis. Answer: Computed through:
, -mass or volume of the sample to be analyzed
-measurement of some quantity that is proportional to the amount of
analyte in the sample
◉ Gravimetric methods. Answer: determine the mass of the analyte or
some compound chemically related to it
◉ Volumetric method. Answer: the volume of a solution containing
sufficient reagent to react completely with the analyte is measured
◉ Electroanalytical methods. Answer: involve the measurement of
such electrical properties as *voltage*, *current*, *resistance*, and
*quantity of electrical charge*
◉ Spectroscopic methods. Answer: based on measurement of the
interaction between electromagnetic radiation and analyte atoms or
molecules or on the production of such radiation by analytes
◉ Heterogeneous. Answer: the constituent parts of a material can be
distinguished visually or with the aid of a microscope (coal, animal
tissue, soil)
◉ Assay. Answer: process of determining how much of a given
sample is the material indicated by its name
