equipment to make limited to those in Specific
measurements, depending Objective 1.2 above.
upon the degree of
accuracy required.

2. Titrimetric (Volumetric) Methods of Analysis

Students should be able to:

2.1. explain the basic principles
upon which titrimetric
analyses are based;

primary standards.

Definition of primary
standards required.

2.3. use data obtained from
potentiometric
thermometric and
conductrimetric methods
