Scheme of Examination

The duration of exam will be 4 hrs.

The following exercises will be set in the examination

  • Inorganic Chemistry-Semi micro analysis                                           42 marks
  • Physical Chemistry                                                                              16 marks
  • Viva                                                                                                      12 marks

         Total                                                                                                 70 marks

Qualitative Mixture Analysis:

  1. The exercise carries 42 marks.
  2. Seven marks shall be awarded for each radical correctly reported and properly recorded which are further divided as-two marks will be awarded for each correct radical if only dry test or preliminary tests are given, three marks may be awarded to a candidate if she has approached in a systematic and correct manner towards the analysis of basic and acid radicals. Two marks shall be awarded for merely reporting the correct radical.

Viva:

Oral questions shall generally be asked over the work assigned to the candidate.

The purpose is to find out as to what extent the candidate has understanding the basic principles of chemistry of the practical work.
