Marking Scheme

 

The duration of exam will be 4 hrs.

 The following exercises will be set in the examination

  • Inorganic Chemistry-Semi micro analysis                                  52 marks
  • Viva                                                                                             08 marks
  • Record                                                                                        10 marks

                                                                              Total            70 marks

Qualitative Mixture Analysis:

  1. The exercise carries 52 marks.
  2. Eleven marks shall be awarded for each radical correctly reported and properly recorded which are further divided as-four marks will be awarded for each correct radical if only dry test or preliminary tests are given, five 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. Eight 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.
