Credit: 1 (Allocated Hours: 50 (P - 30, Independent learning-20))
1. To provide an opportunity to apply theories taught in the class (FST 1113) room and to test their validity
2. To provide opportunities to get hands-on experience and familiarize with basic laboratory apparatus, equipment & chemicals and safety practices in chemistry laboratories
3. To enhance the skills in applications of chemistry required for understanding topics and issues in Food Science & Technology
4. To improve recording data/ writing of laboratory reports
on successful completion of this course students should be able to;
1. Perform experiments and carry out related calculations with confidence by applying the theoretical knowledge
2. Construct conclusions based on observations
3. Propose mechanisms to explain observations and changes that occur in chemical experiments in the context
4. Suggest an appropriate method of analysis upon a given sample
5. Write lab reports with proper presentation of data
