6.2) Definition of polymer, monomer and degree of polymerization.
6.3) Brief introduction to addition and condensation polymers with suitable examples(PE,PS, PVC, Teflon, Nylon -66 and Bakelite)
6.4) Definition of plastics, thermo plastics and thermo setting plastics with suitable examples, distinctions between thermo and thermo setting plastics.
6.5) Applications of polymers in industry and daily life.
LIST OF PRACTICALS
1.) Estimation of total hardness of water using standard EDTA solution.
2.) Estimation of total alkalinity of given water sample by titrating it against standard sulphuric acid solution.
3.) Proximate analysis of solid fuel.
4.) Estimation of temporary hardness of water sample by O Hener’s Method.
5.) Determination of flash and fire point of given lubricating oil using Able’s flash point apparatus.
INSTRUCTIONAL STRATEGY
Teachers may take help of various models and charts while imparting instructions to make the concept clear. More emphasis should be laid on discussing and explaining practical applications of various chemical process and reactions. In addition, students should be encouraged or motivated to study those processes in more details, which may find practical application in their future professional career.
