Course Objective

The Engineering Chemistry Laboratory provides students with hands-on experience in fundamental chemical analysis techniques including water quality assessment, polymer synthesis, physical property measurements, material characterization, separation techniques, and analytical methods essential for engineering applications.

Through these experiments, students develop practical skills in handling laboratory equipment, following standard protocols, interpreting experimental data, and understanding the significance of chemical principles in various engineering contexts.

These practical experiences enhance students' analytical thinking, experimental precision, and ability to apply theoretical knowledge to solve real-world engineering problems related to water treatment, material selection, quality control, and environmental considerations.

Pre-requisites

Chemistry knowledge at 10+2 level (CBSE)
Mathematics at 10th standard CBSE level
Knowledge of algebraic operations (manipulating equations, solving linear equations)
