Quantitative analysis

Quantitative analysis:
• The quantitative amounts of the chemical elements or of certain
compounds in the analyzed substance. Along with specificity
and sensitivity, the most important characteristic of every
method of quantitative analysis is accuracy.

Volumetric analysis:
• analytical methods and techniques in which the amount of a substance in a
sample is determined by measuring the volume of a liquid or gas;
especially any method using titration
The reaction of the known substance with the substance to be analyzed,
occurring in aqueous solution, is generally conducted by a titration
procedure

Type of Titrations:
Classified into four types based on type of reaction involved;
1) Acid-base titrations: in which an acidic or basic titrant reacts with an analyte
that is a base or an acid.
2) Complex metric titrations: Complexometric titrations are based on the
formation of a complex between the analyte and the titrant. The chelating
agent EDTA is commonly used to titrate metal ions in solution.
3) Redox titrations: where the titrant is an oxidizing or reducing agent
4) Precipitation titrations: in which the analyte and titrant react to form a
precipitate..
