25
Q

FACTORS TO BE CONSIDERED IN QUANTITATIVE ANALYSIS

A
  • The level of accuracy required
  • The number of samples to be analyzed
  • The complexity of the sample
  • The number of components in the sample
26
Q

Procedures in Qualitative Analysis

A

-Precipitation, extraction, and distillation

27
Q

Procedures in Quantitative Analysis

A
  • Gravimetric Methods
  • Volumetric Methods
  • Volumetric Analysis
  • Electroanalytical Methods
  • Spectroscopic Methods
28
Q

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

A

Gravimetric Methods

29
Q

the volume of a solution containing sufficient reagent to react completely with the analyte is measured.

A

Volumetric Methods

30
Q

is a chemical analytical procedure based on measurement of volumes of reaction in solutions. It uses titration to determine the concentration of a solution by carefully measuring the volume of one solution needed to react with another.

A

Volumetric Analysis

31
Q

involve the measurement of such electrical properties as voltage,
current, resistance and quantity of electric charge.

A

Electroanalytical methods

32
Q

are based on measurement of the interaction between electromagnetic radiation and analyte atoms or molecules or on the production of such radiation by analytes.

A

Spectroscopic Methods

33
Q

Types of Analytical Methods

A
  1. Classical Methods
  2. Instrumental Methods
34
Q

Procedures in Classical Methods

A
  • Separations: precipitation, extraction, distillation
  • Qualitative: boiling points, melting points, color, odor, solubilities
  • Quantitative: titrations, gravimetric analysis
35
Q

Procedures in Instrumental Methods

A
  • Separations (Chromatography, electrophoresis, etc.)
  • Qualitative or Quantitative (Spectroscopy, electrochemical methods, mass spectrometry, NMR, radiochemical methods, etc.)
36
Q

Standardized system of units used by scientists all over the world.

A

International System of Units

37
Q

a description of how
close a measurement is to the true
value of the quantity measured

A

Accuracy

38
Q

the exactness of a measurement

A

Precision

39
Q

origins of the word Stoichiometry

A

Greek word stoicheion (element) and metron (measure)

40
Q

Is the quantitative study of reactants and products in a chemical reaction.

A

Stoichiometry

41
Q

signifies the quantitative(amount of the
substance) relationships among the reactants and the products in a chemical reaction.

A

Stoichiometry

42
Q

is the sum of the atomic masses of all the atoms in an element or compounds.
