Marking Scheme

The duration of examination will be 4 hrs.

The following excercise will be set in the examination

  • Inorganic Chemistry-Semi micro analysis                                         60 marks
  • Viva                                                                                                    10 marks

                                                                                    Total            70 marks

Qualitative Mixture Analysis:

  1. The exercise  carries 60 marks. Not more than one typical combination of acid radical or two basic radicals of the same group will be given in a mixture of six radicals consisting of three basic and three acidic radicals including interfering radicals.
  2. Nine marks shall be awarded for each radical correctly reported and properly recorded which are further divided as-three marks will be awarded for  each correct radical if only dry test or preliminary tests are given, four 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.
  3. Six marks shall be provided for correct observation and detailed reporting of the radicals.

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.
