Atomic Structure, Periodic Table and Chemical Bonding (14 periods) 2. Fuelsand Lubricants (18 periods) 3. Water (14 periods) 3.1 Demonstration of water resources on Earth using pie chart. 3.2 Classification of water – soft water and hard water, action of soap on hard water, types of hardness, causes of hardness, units of hardness – mg per liter (mgL-1) and part per million (ppm) and simple numerical, pH and buffer solutions and their applications. 3.3 Disadvantages caused by the use of hard water in domestic and boiler feed water. Primming and foaming and caustic embrittlement in boilers. 3.4 Removal of hardness -Permutit process and Ion-exchange process. 3.5 Physico-Chemical methods for Water Quality Testing a) Determination of pH using pH meter, total dissolved solids (TDS) b) Testing and Estimation of- alkalinity, indicator their types and application total hardness by EDTA method and O’Hener’s Method. (chemical reaction of EDTA method are excluded). c) Understanding of Indian Water Quality standards as per WHO 3.6 Natural water sterilization by chlorine and UV radiation and reverse osmosis. 3.7 Municipality waste water treatment.
