Where it gets hard
The units students slow down on, and what makes each one heavy.
- Module 2: Basic Concept of Titrmetric Analysis
Unit 4: Complexometric and Precipitation Titrations
The calculations involved in complexometric titrations, especially with EDTA, require a strong understanding of equilibrium constants and conditional formation constants, which can be challenging to apply in practical problems.
- Module 3: Selected Analytical Techniques
Unit 1: Physicochemical Analysis (UV)
Understanding the instrumentation of spectrometry requires knowledge of physics concepts like electromagnetic radiation and the function of different components such as monochromators and detectors, which can be difficult for students without a strong physics background.
