COURSE OUTCOME

At the end of this course, the incumbent will be able:

  1. Remembering:  Keep in mind the fundamental chemistry regarding laboratory safety, preparation of solution and relevant theory behind the experiments.
  2. Understanding: Describe how to perform an experiment. Explain the scientific logic behind different experiments.
  3. Applying:  Use diverse experimental procedure to determine the unknown strength of any solution and different characteristics of matters like surface tension, viscosity etc.
  4. Analyzing: Analyze different real time problems and categorize them during the process of solving through various types of titration method such as hardness of water, standardization using conductivity meter, pH-meter, viscometer etc.
  5. Evaluating: Justify and make gradation of above mentioned experimental procedures to find the optimal solution for multidisciplinary engineering problems.
  6. Creating: Devise a practical model and build a corridor through which innovative ideas can be evolved to create newer problems that will be accepted by academia, research as well as industries.
