EN3301 subject code deals with the Environmental Chemistry syllabus of B.E Environmental Engineering. In the second year, it is included in the semester III. This subject deals with the statistics and probability concepts to explore. In this article, we include textbooks and references to guide you to some more extent.
We aim to provide a detailed syllabus of EN3301 Environmental Chemistry. You can find unit-wise concepts and can easily make your preparations for examinations. It wouldn’t be difficult to find all the requirements in one place for the subject syllabus. This motto makes us provide this information to make it easy for you. Hope this information is useful. Don’t regret to share it with your classmates.
If you want to know more about the syllabus of other branches including B.E Environmental Engineering connected to an affiliated institution’s four-year undergraduate degree programme. We provide you with a detailed Year-wise, semester-wise, and Subject-wise syllabus in the following link B.E Environmental Engineering Syllabus Anna University, Regulation 2021.
Aim Of Concept:
- To educate the students in the area of water, air and soil chemistry
- To explain the theoretical basis and observational methods for study of contaminants and interactions in the environment
