CHEMISTRY – I

LIST OF EXPERIMENTS

1.      Introduction to Chemistry Lab (the teachers are expected to teach fundamentals like Primary, Secondary Standard Solutions , Normality, Molarity, Molality etc and laboratory ware used, error ,accuracy, precision, Theory of indicators, use of volumetric titrations                                                     

2.      Introduction to Volumetric Analysis:

           The Teacher has to perform four types of volumetric titrations and will explain about the                

           working of Indicators .(The Teacher has to call the students at random to perform the titrations)            

2.  ANALYSIS OF WATER                                                                                                                         

     Estimation of :

     a.TOTAL HARDNESS  BY EDTA METHOD       b.TURBIDITY           c.CONDUCTIVITY

     d. pH        e.TOTAL DISSOLVED SALTS

     f.FLORIDES,CHLORIDES AND NITRATES ( USING ION ANALYSER)

    g. DISSOLVED OXYGEN         h.BACTERIAL COUNT

     The student has to get his water sample and the teacher has to explain the analysis and the results are to be compared with the INDIAN STANDRDS.

3.CONSTRUCTION OF GALVANIC CELL                                                         

    Based on the  position of the metals in the electrochemical  series  a model Electrochemical  

   Cell is constructed and the values are determined and effect of metal ion concentration, 

  Temprature etc. on emf are calculated.
