Introduction to Analytical Chemistry

Which reveals chemical identity of elements and compounds in a sample?

• Quantitative Analysis

• Qualitative Analysis

Which determines the relative amounts of each substance in a sample?

• Quantitative Analysis

• Qualitative Analysis

These substances delay the rate of chemical reaction.

• enzymes

• catalysts

• inhibitors

Check all that applies to the scope of Analytical Chemistry.

• separation

• identification

• quantification

• comprehension

• elaboration

Analytical chemistry is applied in all areas of science, industry, and medicine.

• True

• False

All sub-disciplines rely on Analytical Chemistry to function.

• True

• False

Which determine the mass of analyte or some compound chemically related to it?

• Volumetric methods

• Gravimetric methods

• Electroanalytical methods

• Spectroscopic methods

These methods are based on interaction of electromagnetic radiation with analyte atoms & molecules.

• gravimetric methods

• volumetric methods

• spectroscopic methods

• electroanalytical methods

These are portions of a material of approximately the same size that are carried through an analytical procedure at the same time and in the same way.

• analytes

• samples

• replicates

• duplicates

Which causes an error in an analysis by enhancing or attenuating (making smaller) the quantity being measured?

• improper use of units

• improper handling

• poor reading

• interference
