This book, M.Sc. II Practical Chemistry Semester III and IV as per New Syllabus NEP 2020, is designed to provide a comprehensive understanding of both theoretical and practical aspects of analytical chemistry, specifically tailored to align with the New Education Policy (NEP) 2020. It aims to equip learners with essential knowledge and skills, encompassing both classical and modern instrumental methods, required for the analysis of diverse samples such as soil, water, and commercial products. Emphasising foundational principles, this book prepares students for critical roles in environmental and industrial chemistry by delivering systematic training in laboratory techniques, sample preparation, and instrumental handling.
Through this book, learners will gain hands-on experience in basic laboratory operations, including non-instrumental and instrumental methods for analysing a variety of samples. It covers all facets of sample preparation and aims to hone the learners’ ability to conduct accurate calculations to generate reliable results. Dedicated sections on soil and water analysis ensure that students understand essential practices, from detecting and quantifying analytes to performing quality assessments on environmental samples. The book also provides an introductory yet thorough exposure to the use of analytical techniques in commercial quality assessment.
Beyond the basics, this book aims to foster an understanding of research methodology, instilling an awareness of the importance of research and its application in problem-solving. Learners will be introduced to identifying research problems, utilising journal articles and digital resources, and developing systematic research plans, bridging theoretical knowledge with experimental implementation.
In essence, M.Sc. II Practical Chemistry as per New Syllabus NEP 2020 seeks to create a solid foundation in practical chemistry. It encourages analytical thinking and provides learners with the tools to apply theory to real-world situations, preparing them to contribute meaningfully in both academic and industrial research environments. This preface serves as an invitation for learners to engage in an immersive journey that blends technical expertise with critical research skills, essential for their future careers in chemistry and beyond.
